Question

i know this is math but no one is helping me on physics so is any one in physics and can help me
1. What accounts for an increase in the temperature of a gas that is kept at constant volume? (1 point)
Energy has been removed as heat from the gas.
Energy has been added as heat to the gas.
Energy has been removed as work done by the gas.
Energy has been added as work done on the gas.
2. When an ideal gas does positive work on its surroundings, which of the gas’s quantities increases?
(1 point)
temperature
volume
pressure
internal energy

Answer 1

3. Which thermodynamic process takes place when work is done on or by the system but no energy is
transferred to or from the system as heat? (1 point)
isovolumetric
isobaric
adiabatic
isothermal
4. Which thermodynamic process takes place at a constant temperature so that the internal energy of a
system remains unchanged? (1 point)
isovolumetric
isobaric
adiabatic
isothermal

5. An ideal gas system undergoes an adiabatic process in which it expands and does 20 J of work on its
environment. How much energy is transferred to the system as heat? (1 point)
–20 J
0 J
5 J
20 J
6. An ideal gas system undergoes an isovolumetric process in which 20 J of energy is added as heat to the
gas. What is the change in the system’s internal energy? (1 point)
–20 J
0 J
5 J
20 J
7. Which of the following is a thermodynamic process in which a system returns to the same conditions under
which it started? (1 point)
an isovolumetric process
an isothermal process
a cyclic process
an adiabatic process

Oh dear lord all those questions.. @_@
I hope you weren't expecting me to answer those Rad >.<
