Why would cooling the gas in an air balloon make the balloon contract?

== == According to Charles's Law, "At constant pressure, the volume of a given mass of an ideal gas increases or decreases by the same factor as its temperature (in Kelvin) increases or decreases." Therefore, if the temperature of the gas is decreased, the volume of the gas will decrease proportionally, and the balloon will contract.


What happens to the intermolecular spaces when some energy is removed from a gas or liquid it decreases it increases it is not affected or increases and decreases alternatively?

By removing energy, what you mean is reducing temperature. A gas or liquid will contract as it gets colder, and intermolecular spaces will decrease.


How does a fluid-filled thermometer works?

As the temperature of a fluid increases, its volume increases, and as the temperature decreases, its volume decreases. Since the liquid in a thermometer is in a closed container, the fluid rises when the temperature increases and lowers when the temperature decreases.


What is the most important factor affecting seawater density?

The most important factor affecting seawater density is its temperature. As temperature increases, seawater density decreases, causing it to expand and rise. Conversely, as temperature decreases, seawater density increases, causing it to contract and sink.


When the temperature of an object decreases what happens to the molecules?

In every liquid (with the exception of water) the molecules, when the temperature decreases, contract.


How is volume and density affected when the temperature is decreased?

In general when temperature is decreased the volume decreases and the density increases. This is not true for water around freezingg temperatures, the volume increases and the density decreases and ice floats.


If the core temp of a star decreases what happens to the radius?

If the core temperature of a star decreases, it will contract, causing the core to become denser. This contraction may lead to an increase in temperature in the outer layers, causing the star to expand its radius to re-establish equilibrium.


What happens to the volume of an object when temperature decrease?

When the temperature of an object decreases, its volume tends to decrease as well. This is because as the temperature drops, the particles in the object move slower and closer together, causing the object to contract and reduce in volume.


Why does density vary with temperature?

In general as things get hotter they expand, and conversely when they cool they contract. This is most noticeable for gases. As the mass remains constant because density is mass/volume as volume increases when temperature goes up the density decreases. The opposite occurs when temperature drops.


What is the only way the density of a pure substance can change?

The density of a pure substance can change by altering its temperature. As temperature increases, most substances expand and therefore decrease in density, whereas as temperature decreases, most substances contract and increase in density.


How does temperature affect s thermometer?

Temperature affects a thermometer by causing the liquid or material inside to expand or contract, leading to a change in volume. This change in volume is measured by the scale on the thermometer, so as temperature increases or decreases, the level of the liquid or material inside the thermometer will rise or fall accordingly.


Explain how air pressure is related to temperature?

As air temperature increases, air molecules gain more energy and move faster, causing the air to expand and become less dense. This leads to a decrease in air pressure since the air molecules are more spread out. Conversely, as air temperature decreases, air molecules lose energy and move slower, causing the air to contract and become more dense, resulting in an increase in air pressure.
