If the volume of a container of gas is reduced, what will happen to the pressure inside the container?
2 answers:
Answer: a. The pressure will increase.
Explanation:
Boyle's Law: This law states that pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.
(At constant temperature and number of moles)
where,
= initial pressure of gas
= final pressure of gas
= initial volume of gas
= final volume of gas
Thus as volume of the container will be reduced, the pressure would increase.

Explanation:
Hello,
In this case, we can compute the change in the solution enthalpy by using the following formula:
Whereas the mass of the solution is 350 g, the specific heat capacity is 4.184 J/g °C and the change in the temperature is 1.34 °C, therefore, we obtain:
It is important to notice that the mass is just 350 g that is the reacting amount and by means of the law of the conservation of mass, the total mass will remain constant, for that reason we compute the change in the enthalpy as shown above, which is positive due to the temperature raise.
Best regards.
