Step-by-step explanation:
According to the ideal gas equation, PV = nRT.
As, volume is kept constant then relationship between pressure and temperature is directly related.
That is, pressure is directly proportional to temperature.
As we are adding heat to the gas and it means that we are increasing the temperature. Hence, there will also be increase in pressure.
Thus, we can conclude that a sample of nitrogen gas is in a sealed container with a constant volume. Heat is added to the gas. The pressure increases.
