Questions & Step-by-Step Solutions
What happens to the density of a gas if its temperature is increased at constant pressure?
Step 1: Understand that density is the mass of a substance divided by its volume (Density = Mass/Volume).
Step 2: Know that the ideal gas law states that for a gas at constant pressure, if the temperature increases, the volume of the gas must also increase.
Step 3: Since the mass of the gas remains constant, when the volume increases and the mass stays the same, the density must decrease.
Step 4: Conclude that if the temperature of a gas increases at constant pressure, its density decreases.
