Can there be a temperature colder than 0 Kelvin?
Why can't the temperature be less than 0 Kelvin?
Why is -273.15 °C known as absolute zero temperature? Why is absolute zero temperature -273.15 degrees? What is so special about this number? Why do we not use the sign of degree in Kelvin but use on Fahrenheit and Centigrade although they all are the measurements of temperature? CAN we achieve absolute zero? What is negative temperature then? Why do we say that negative temperature is hotter than infinite temperature? Wouldn't that mean it has infinite heat (and energy)? What is the relationship between Celsius, Fahrenheit and Kelvin? What happens at absolute zero temperature? What does No Temperature mean? Why does the heat always flow from high to low temperature? What is the freezing point of water in Kelvin? How was it determined? What is temperature? Why can't we just add 32 degrees to get from Celsius to Fahrenheit? Why does it have to be more complicated? Is it normal to not like room temperature? What is temperature coefficient? Is it theoretically possible to achieve the absolute zero temperature? Why thermal conductivity of water decreases with increase in temperature? Why is the human body temperature as it is? Why does the thermal conductivity of metals decrease with an increase in temperature? How can the temperature in outer space be described? Why is it so that surface temperature of a substance is low compared to its core region? Why are conductors called positive temperature coefficients? Why does our body prefer a room temperature of 21 degrees while the body itself prefers to be 37 degrees? Is 96.5 degrees Fahrenheit considered a normal temperature for a child? Why or why not? Why is heating easier than cooling? Can the human body produce a temperature of 10,000 degrees? Why do we have different scales of measuring temperature (e.g. Fahrenheit, Celsius and degree)? Why is specific heat at constant pressure greater than specific heat at constant volume? What is the lowest temperature in the universe? What is the difference between heat & temperature? How is temperature measured?
