Question:medium
5 mol of hydrogen gas is heated from 30°C to 60°C at constant pressure. The heat given to the gas is (given \( R = 2 \, \text{cal/mol deg} \)):
5 mol of hydrogen gas is heated from 30°C to 60°C at constant pressure. The heat given to the gas is (given \( R = 2 \, \text{cal/mol deg} \)):
Show Hint
For a gas heated at constant pressure, the heat required depends on the number of moles, heat capacity, and the temperature change.
