Balloons are filled with gas and gas expands when temperature increases. Gas also condenses when the temperature is lowered. This is due to Charles' law.
it expands and contracts when the temperature drops, the mercury contracts...when the temperature increases, the mercury expands
The object expands
The object expands
no ,Because when the temperature increases the metal expands and when the temperature is low the metal contracts
When the glass of a buret expands due to an increase in temperature, the diameter of the bore actually increases. This is because the material expands uniformly in all directions, including the internal diameter of the bore. Consequently, as the glass expands, the volume capacity of the buret increases, allowing for more liquid to be held.
Temperature and volume vary directly, so if temperature decreases, so does volume. Volume decreases because the measure of the average kinetic energy of the gas particles (temperature) is decreasing also. When that happens, a gas cannot expand, and will decrease.
When the temperature increases, the mercury in a thermometer expands and rises up the column because the volume of the liquid increases with temperature. This expansion is linear and is used to indicate the rise in temperature on the thermometer scale.
The material in the thermometer expands and contracts as temperature increases or reduces.
Becomes lighter and rises, the principle of hot air balloons.
because atoms expands when temperature increases in result physical changes.
When the temperature increases, the mercury inside the thermometer expands due to thermal expansion, causing the level of mercury to rise in the thermometer tube. This results in a higher reading on the scale of the thermometer, indicating a higher temperature.
A thermometer uses a liquid, such as mercury or alcohol, that expands and contracts with temperature changes. As the temperature increases, the liquid expands, causing it to rise up a calibrated tube. The level of the liquid in the tube corresponds to the temperature reading indicated on the scale.
