Answer:
reduces
Explanation:
According to Boyle's law, when the pressure of a gas increases at constant temperature the volume reduces.
Boyle's law states that "the volume of fixed mass of a gas is inversely proportional to the change in pressure if the temperature is constant".
- It suggests that at constant temperature, if pressure increases, temperature reduces.
Mathematically, it is expressed as;
P1 V1 = P2 V2
P and V are pressures
1 and 2 are initial and finals state.
1. the noble gas krypton (Kr).
The total change in internal energy would simply be
calculated using the formula:
ΔU = -P (V2 – V1) + ΔH
where ΔU is the change in internal energy; P is constant
pressure = 30 atm = 3,039,750 Pa; V2 is final volume = 2 L = 0.002 m^3; V1 is
initial volume = 7.20 L = 0.0072 m^3; while ΔH is the heat = -74,400 J (heat
released so negative)
Therefore:
ΔU =-3,039,750 Pa * (0.002 m^3 - 0.0072 m^3) + (- 74,400
J)
