Express your answer using two significant figures You may want to review(L pages 331-332) Submit My Answers Give Up Part B How does the temperature of the gas change? O Decreases Does not change 0 It is impossible to determine. Submit My Answers Give UpExplanation / Answer
Solution:
A)
As we know;
Energy in = Energy out
=> 28 J = 18 J + Thermal energy
=> Thermal energy = +10 J
B)
As we know;
Thermal energy refers to the internal energy present in a system due to its temperature.
as,
Thermal energy = +10 J
=> Increase in internal energy will result in an increase in temperature.
=> Temperature of the gas increases!
