An ideal gas is held at a constant temperature of 320 K as it expands slowly from a volume of 0.70 m³ to 4.5 m³. As the gas
expands, it does 280 J of work.
What is the change in the internal energy AU of the gas during this process?
AU =
How much heat Q is absorbed by the gas as it expands?
Q =
x10

Expert Solution

Step 1

For an ideal gas, internal energy is only the function of temperature. And given that we have isothermal process ( constant temperature) so dU= 0

i.e. change in internal energy is zero.
