Absolute zero degree temperature is not the temperature of zero eneregy' - Explain.

The absolute temperature (Kelvin scale) T is related to the temperature t_c on the Celsius scale by T_C = 7- 273.15 Why do we have 273.15 in this relation, and not 273.16

The following graph shows the temperature forecast and the actual temperature for each day of a week. On which day did the actual temperature differ the most from the forecast temperature?

The following graph shows the temperature forecast and the actual temperature for each day of a week. On which days was the forecast temperature the same as the actual temperature?

The following graph shows the temperature forecast and the actual temperature for each day of a week. What was the maximum forecast temperature during the week?

The following graph shows the temperature forecast and the actual temperature for each day of a week. What was the minimum actual temperature during the week?

On reducing the volume of a gas at constant temperature the pressure of the gas increases.Explain on kinetic theory.

For a zero order reaction will the molecularity be equal to zero? Explain.

Can potential be zero where electric field is not zero ?

Explain why: n optical pyrometer (for measuring high temperatures) calibrated for an ideal black body radiation gives too low a value for the temperature of a red hot iron piece in the open, but gives a correct value for the temperature when the same piece is in the furnace

A carnot's engine has an efficiency of 50% when its sinks temperature is 27 degree C what must be the change in its source temperature for increasing its efficiency of 60% ?
