What causes a substance to expand?
When a substance is heated, the kinetic energy of its molecules increases, causing them to move faster and further apart. This results in an expansion of the substance's volume. Conversely, when a substance is cooled, the molecules slow down and move closer together, causing the substance to contract.
What is the value of m in the equation qmct?
The value of m in the equation qmct represents the mass of the substance being heated or cooled.
What are two ways to change the state of a substance?
One way to change the state of a substance is through heating or cooling it, which can lead to melting, freezing, evaporation, or condensation. Another way is applying pressure, which can cause a substance to change from a solid to a liquid or a liquid to a gas.
What substance changes from a gas to a liquid?
Water is a substance that changes from a gas (water vapor) to a liquid (water) through a process called condensation. This change in state occurs when the temperature of the water vapor decreases, causing it to lose energy and form liquid water droplets.
If air is compressed and cooled sufficiently it becomes a substance?
If air is compressed and cooled, the temperature of the air will become negative. Now depending on how much humidity there is in that air being compressed we might get some water droplets as it is being cooled. Carbon dioxide when compressed and cooled we get dry ice.
What happens to the particle in a substance when it is cooled?
i. dont.know
What is happening to the molecules of a substance when they are heated or cooled?
When a substance is heated, the molecules gain kinetic energy and move faster, causing them to vibrate and collide more frequently, which increases the temperature of the substance. When a substance is cooled, the molecules lose kinetic energy and move slower, reducing the frequency of collisions and vibrations, which lowers the temperature of the substance.
What substance would gas change into if it was cooled?
a liquid then if cooled further it would turn into a solid a liquid then if cooled further it would turn into a solid
How much energy is released when a substance is cooled to its original temperature?
When a substance is cooled to its original temperature, no energy is released. Cooling a substance typically involves removing energy from the substance, but this process does not generate energy. The energy removed is used to lower the temperature of the substance.
Is the expansion of a substance due to heat?
YES, as far as I'm concerned, a substance expands when heated and contracts when cooled.
When a substance is cooled down it usually expands true or false?
False. Most substances contract or shrink when they are cooled down because cooling reduces the kinetic energy of the particles in the substance, causing them to move closer together.
What does thermochromatic mean?
it refers to a substance undergoing a reversible change of colour when heated or cooled
When a substance is cooled what happens to its particles how does cooling affect the volume of the substance?
When a substance is cooled, its particles lose kinetic energy and move more slowly, causing them to come closer together. This reduction in particle movement typically results in a decrease in the volume of the substance, as the particles occupy less space. In most cases, this leads to the substance contracting; however, exceptions exist, such as water, which expands upon freezing.
Which crystals most likely formed from molten material that cooled and solidified most rapidly?
If a substance is cooled and solidified rapidly, generally amorphous material is obtained instead of crystals. In order to obtain good quality crystals, if is better that the substance solidifies slowly
When meterials are cooled they get smaller?
Generally, yes. The atoms in a substance move around much less the cooler they are, so the substance takes up less space.
How do liquids act when they are cooled?
When liquids are cooled, their molecules slow down and move closer together, which causes them to contract or solidify, depending on the substance. This process is known as freezing or solidification. The specific behavior of a liquid when cooled will depend on its chemical composition and temperature.
Could you give me an example using the word solidify?
If a substance is cooled enough, it will solidify at its freezing point.
