g class, we discussed piston-cylinder systems (i. e., cylinders with freely moving pistons). A reaction in one of these systems results in a change in volume from 4 to 5 L and a change in temperature from 400 K to 390K. When considering the energy balance on the reaction, we can say that the work term has a sign, and the enthalpy change of the reaction has a sign.

colorless gas, exhibiting a blue glow when placed in an electric field

b) solid

its a type of rock

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
