Can you discribe thermal expansion of gases? |
|
Answer» Yours welcome Thanks In case of gases, when balloon is partially inflated in a cool room it expands to full size when put in warm water. This all is due to thermal expansion. So, increase in dimension of a body due to increase in temperature is thermal expansion. The expansion in is called linear expansion.A gas expands when heated and condenses when cooled. Charles\' Law predicts a four-fold decrease in the volume of a gas that is cooled from room temperature to the temperature of liquid nitrogen (77 K). ... Removing the balloon exposes the cold balloon to higher temperatures. |
