Q1
What happens to the density of a gas if its temperature is increased at constant pressure?
Density increases
Density decreases
Density remains the same
Density fluctuates
According to the ideal gas law, if temperature increases at constant pressure, volume increases, leading to a decrease in density.

Q
Q: What happens to the density of a gas if its temperature is increased at constant pressure?
Solution: According to the ideal gas law, if temperature increases at constant pressure, volume increases, leading to a decrease in density.
Steps: 4
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.
