A cylinder of volume `10 m ^(3)` contains hydrogen gas at 300 K. What is the quantity of heat required to raise the temperature of the gas to 303 K? Using this energy a body of mass m can be lifted to a height of 10 m. What is the body ? Density of hydrogen is `8. 9 xx 10 ^(-2) Kg //m ^(2)- C _(v) = 20. 4 J mol ^(-1) K ^(-1).`

Explanation

To solve the problem step by step, we will break it down into two parts: calculating the heat required to raise the temperature of the hydrogen gas and then using that heat to find the mass of the body that can be lifted to a height of 10 m.

### Step 1: Calculate the change in temperature (ΔT)
Given:
- Initial temperature (Ti) = 300 K
- Final temperature (Tf) = 303 K

The change in temperature (ΔT) is calculated as:
