Questions & Step-by-Step Solutions
What is the effect of increasing temperature on the density of a gas?
Step 1: Understand what density is. Density is how much mass is in a certain volume. For gases, it is usually measured in grams per liter (g/L).
Step 2: Know that temperature is a measure of how hot or cold something is. When temperature increases, the energy of the gas particles also increases.
Step 3: Realize that when gas particles gain energy from heat, they move faster and spread out more. This means they take up more space.
Step 4: Since the gas is now occupying a larger volume but the mass remains the same, the density (mass divided by volume) decreases.
Step 5: Conclude that increasing the temperature of a gas causes it to expand, which leads to a decrease in its density.
