Answer:
The change in energy of the gas during the process is 
joules.
Explanation:
We can represent this process by the First Law of Thermodynamics, in which gas does work on its surroundings and absorbs heat from there to describe its change in energy. In other words:
Where:
- Heat absorbed by the gas, measured in joules.
- Work done by the gas, measured in joules.
- Change in energy, measured in joules.
If we know that 
and 
, the change in energy of the gas is:
The change in energy of the gas during the process is joules.
Answer:
A
Explanation:
Actual output divided by the effective capacity. It is the ratio of output to effectiveness
The answer is B frequency. When frequency increases more wave crests pass a fixed point each second. That means the wavelength shortens. So, as frequency increases, wavelength decreases
