thermodynamics

Question 1

2 ways of increasing the internal energy of a body

Answer 1

1) by heating the body
2) by doing work on the body

Question 2

first law of thermodynamics

Answer 2

The increase in internal energy is equal to the sum of heat energy added to the body ▲q and the work done on it ▲W.

Question 3

Heating

Answer 3

heating is the process that occurs when the internal energy of a system is increased due to energy transfer to it from a system that is at a higher temperature.

Question 4

Work done by gas

Answer 4

W = F▲x
p = F/A
W = pA▲x
W = p▲V

Question 5

area under a pv graph

Answer 5

gives work done

Question 6

Thermodynamic processes

Answer 6

isothermal
isochoric
isobaric

Question 7

isothermal process

Answer 7

Isothermal process is a thermodynamic process which takes place at a constant temperature,

Question 8

isochoric process

Answer 8

Isochoric process is a thermodynamic process in which the volume of the system stays constant

Question 9

isobaric process

Answer 9

isobaric process is a thermodynamic process in which the pressure of the gas stays constant

Question 10

thermodynamic cycle

Answer 10

Is represented by a closed loop on a PV diagram .
