<span>The pressure exerted by a gas on its container is directly proportional to the absolute temperature of the gas.
This result is known as "Gay-Lussac law", which states that for an ideal gas with fixed volume (like the gas in the container), the ratio between pressure and absolute temperature of the gas is constant:
</span>
<span>where p is the pressure of the gas and T its absolute temperature.</span>

The work done in lifting the hamburger is equal to the increase in gravitational potential energy of the hamburger, given by
where
m=0.1 kg is the mass of the hamburger
is the gravitational acceleration
is the increase in height of the hamburger
Substituting numbers into the equation, we find
So, the correct answer is
(3) 0.3 J
