What is Surroundings.

During an isothermal expansion, a confined ideal gas does -150 J of work aginst its surroundings. This implies that

In a particular reaction the system absorbs 12kJ of heat and does 3kJ of work on its surroundings. What are changes in internal energy and enthalpy of system?

A sample of gas absorbs 4000 kj of heat (a) if volume remains constant what is DeltaU ? (b) Suppose that in addition to absorption of heat by thesample, the surrounding does 200 kj of work on the sample.What is DeltaU ? (c) Suppose that as the original sample absorbs heat, it expands against atmospheric pressure and does 600 kj of work, on its surroundings. What is DeltaU ?

When a body has the same temperature as that of its surroundings

A system, which can exchange mass as well as energy with its surroundings is called as _______.

A solid sphere and a hollow sphere of the same material and size are heated to the same temperature and allowed to cool in the same surroundings. If the temperature difference between each sphere and its surroundings is T then

A thermally isolated gaseous system can exchange energy with the surroundings. The mode of transfer of energy can be

Ac cording to Newton's law of cooling, the rate of cooling of a body is proportional to (Delta theta)^(n) , where Delta theta is the difference of the temperature of the body and thae surrounding. What is the value of n out of 4,3,2,and 1?

A gas of 0.320 kJ works on its surroundings and absorbs 120 J of heat from the surroundings. Hence, DeltaU is

If the entropy change of a reaction is DeltaS . How will you calculate entropy of its surroundings ?
