temperature temperature in Science. A measure of the ability of a substance, or more generally of any physical system, to transfer heat energy to another physical system. The temperature of a substance is closely related to the average kinetic energy of its molecules. See also Boyle's law.

MASTERING PHYSICAL CHEMISTRY By-- S.K. Standard Temperature and Pressure. Standard temperature is equal to 0 °C, which is 273.15 K. Standard Pressure is 1 Atm, 101.3kPa or 760 mmHg or torr. STP is often used for measuring gas density and volume. At STP 1 mole of any gas occupies 22.4L.

- The average temperature on Earth is about 33.6 F (0.9 C), according to NASA. But temperatures vary greatly around the world depending on the time of year, ocean and wind currents and weather conditions.

Thermodynamic temperature The thermal motions of atoms are very fast and temperatures close to absolute zero are required to directly observe them. For instance, when scientists at the NIST achieved a record-setting cold temperature of 700 nK (1 nK = 10 −9 K) in 1994, they used optical lattice laser equipment to adiabatically cool caesium atoms.

What temperature scale do scientists normally use? The temperature scale commonly used in science is the Celsius or centigrade scale. The Kelvin scale is most often used in the thermodynamic and astronomical fields (and especially when dealing with temperatures close to absolute zero). There are two temperature scales used by scientists. The first scale, Kelvin, is the SI (Standard Unit) or official unit used in certain cases. Informally, and more commonly is the Celsius scale.

Taking the Earthâs Temperature Although the results for the Earth’s temperature are usually given as anomalies, climate scientists have used the measured temperature data to calculate average temperatures. NOAA’s result for the 20th century average land-ocean Earth surface temperature is 13.9 °C.

Whatâs the temperature of space? Just a thought. — Henk. The temperature of the universe is 2.725 +/- 0.002 degrees Kelvin. The Kelvin scale, for those who slept through high school physics, is the same as the Celsius scale, only it starts at absolute zero. In short, the universe is pretty cold. Fortunately, our Milky Way galaxy is about 0.0001 K toastier.

temperature (T) Temperature (symbolized T ) is an expression of heat energy. Temperature can mean different things in different situations. Thermodynamic temperature is a measure of the kinetic energy in molecules or atom s of a substance. The greater this energy, the faster the particles are moving, and the higher the reading an instrument will render.

What is Heat? To review, temperature is a measure of the ability of a substance, or more generally of any physical system, to transfer heat energy to another physical system. If two objects - or if a system and its surroundings - have a different temperature, then they have a different ability to transfer heat.

A Journey to the Center of Earth Temperature. As you start to tunnel beneath the surface, the surrounding rock is cool. Then at about 20 meters down, your instruments report that the rock is getting warmer. For every 40 meters that you descend from that point, the temperature rises 1 Celsius degree.

- Temperature is defined as the average kinetic energy of molecules. Most of the space is empty, no molecules, thus the concept of temperature becomes meaningless. The 3 degree K background radiation does not require atoms as most of the space is empty.

- Temperature is a measure of the average kinetic energy or the amount of heat per particle of a substance. The specific heat of a substance is the energy in joules required to raise the temperature of one gram of a material by one Celsius degree.

- A temperature is an objective comparative measurement of hot or cold. It is measured by a thermometer. Several scales and units exist for measuring temperature, the most common being Celsius (denoted °C; formerly called centigrade), Fahrenheit (denoted °F), and, especially in science, Kelvin (denoted K).

TEMPERATURE Temperature is one of those aspects of the everyday world that seems rather abstract when viewed from the standpoint of physics. In scientific terms, it is not simply a measure of hot and cold, but an indicator of molecular motion and energy flow.

Temperature Definition in Science Several temperature scales exist. In America, the Fahrenheit temperature is most commonly used, though the SI unit Centrigrade (or Celsius) is used in most of the rest of the world.

What is Heat? So now we can meaningfully re-state the definition of temperature. Temperature is a measure of the ability of a substance, or more generally of any physical system, to transfer heat energy to another physical system. The higher the temperature of an object is, the greater the tendency of that object to transfer heat.

Heat and Temperature Initial Definitions. Temperature is a number that is related to the average kinetic energy of the molecules of a substance. If temperature is measured in Kelvin degrees, then this number is directly proportional to the average kinetic energy of the molecules. Heat is a measurement of the total energy in a substance.

Kelvin The kelvin is the primary unit of temperature measurement in the physical sciences, but is often used in conjunction with the Celsius degree, which has the same magnitude. The definition implies that absolute zero (0 K) is equivalent to −273.15 °C (−459.67 °F).

Temperature is a physical property of a system that underlies the common notions of hot and cold; something that is hotter generally has the greater temperature. Specifically, temperature is a property of matter.

Temperature Temperature. Temperature is a measure of the average speed of the random motion of molecules that comprise a substance. Basically, it is a measure of how hot or cold something is. In Chapter 4 we made an important distinction between temperature and heat.Heat is the total molecular motion associated with a substance while temperature is the average motion of molecular that make up a substance.asically, it is a measure of how hot or cold something is.
