charle's law

• Volume


  The amount of space occupied by a substance
• Temperature


  A measure of the average kinetic energy of the particles in a substance
• When the temperature of a fixed amount of gas increases, its volume increases
• When the temperature of a fixed amount of gas decreases, its volume decreases
• Magic in Balloon


  1. Place open end of toy balloon around neck of bottle

  2. Put bottle with attached balloon in bowl of extremely hot water

  3. Observe what happens

  4. Remove bottle from hot water and place in bowl with ice

  5. Observe what happens
• As temperature of a fixed amount of gas increases


  Its volume increases
• As temperature of a fixed amount of gas decreases


  Its volume decreases
• Place the open end of the toy balloon around the neck of the bottle

  If it does not fit tightly, secure it with a rubber band
• Put the bottle with attached toy balloon in the bowl of extremely hot water


  After a few minutes, observe what happens
• Wear gloves or use a pot holder when handling hot bottle
• Most of you might have observed the following phenomena which are all real-life examples of Charles' Law:
• Charles's Law


  The volume of a given mass of gas varies directly with the absolute temperature of the gas when pressure is kept constant
• The absolute temperature scale was devised by the English physicist Kelvin, so temperatures on this scale are called Kelvin (K) temperatures
• Zero on the Kelvin scale corresponds to a complete stoppage of molecular motion
• The graph shows the relation between volume and temperature of a gas at constant pressure
• Charles' law


  For a fixed amount of an ideal gas its volume is directly proportional to its temperature at constant pressure
• Pressure remains constant in Charles' Law
• Charles' Law


  V1/T1 = V2/T2
• Jogging is very difficult in during the month of December compare to the month of April. The reason is simply due to low temperatures our lungs shrink which decrease the human lungs' capacity
• A pressure cooker reducing the cooking time of food
• When ascending or descending in a plane, or taking a subway or train under a deep waterway, your ears "pop," or feel uncomfortable
• When bloated pool floats are pushed into pools, they appear as under-inflated
• Turkey thermometer is placed in the turkey. As the temperature increases and the turkey cooks, the air in the thermometer expands to pop the plunger
• Celsius, Kelvin


  Scale corresponds to a complete stoppage of molecular motion
• Boyle's Law, Charles's Law

  1. If a balloon is filled with a heated gas, its volume must expand

  2. At an elevated temperature the balloon then occupies a larger volume in the same weight as the surrounding air — its density is now less than the cold air and consequently, the balloon begins to rise
• Ping pong ball


  • Restoring its roundness by pumping up and increasing the temperature of the air inside
• Baking


  • Using yeast as an ingredient, the law is applied in delicious bakery products like bread, and cakes
• Deodorant Spray Bottle


  • Storing it below 50°C and keeping it away from direct sun light and ignition to prevent expansion of gas and bursting
