Answer:
From gas laws (pressure law and Boyles law), the pressure exerted by a gas depends on Temperature of the gas and volume of the container.
Explanation:
• P → Pressure exerted by the gas.
• T → Temperature of the gas.
• V → Volume of the container.
• from the expression, pressure exerted by the gas is directly proportional to temperature of the gas and inversely proportional to the volume of the container.

Answer:
0.00420
Explanation:
The equation is Q=mc(T(final)-T(initial), where c is the specific heat, Q is heat supplied, m is mass, T(final) is final temperature and T(initial) is initial temperature (you'll see this written as delta T, which means change in temperature).
2520 = Q
m = 10.0kg; answer choices are in g, not kg, so multiply by 1000 to get m in g; m = 10000 g
Plug in the values you have and solve for c.
2520=(10000)(c)(70-10)
2520=600000c
c=0.0042 j/(gc)
