Q1
According to Charles's Law, how does the volume of a gas change with temperature at constant pressure?
  1. V ∝ T
  2. V ∝ 1/T
  3. V + T = constant
  4. VT = constant

Questions & Step-by-Step Solutions

According to Charles's Law, how does the volume of a gas change with temperature at constant pressure?
  • Step 1: Understand that Charles's Law relates to gases.
  • Step 2: Remember that this law applies when the pressure of the gas is kept constant.
  • Step 3: Know that 'volume' refers to how much space the gas occupies.
  • Step 4: Understand that 'temperature' refers to how hot or cold the gas is, measured in Kelvin (absolute temperature).
  • Step 5: Charles's Law states that if you increase the temperature of the gas, the volume will also increase.
  • Step 6: Conversely, if you decrease the temperature, the volume will decrease.
  • Step 7: This relationship can be summarized as: Volume (V) is directly proportional to Temperature (T) when pressure is constant, written as V ∝ T.
  • Charles's Law – The principle that states the volume of a gas is directly proportional to its absolute temperature when pressure is held constant.
