This is dependent on the amount of heat involved. Low range of heat and the Molecules simply begin to move faster and generate heat within the material. High range of heat and the molecules can be broken apart causing chemical reactions that physically change the material. For example, Hydrogen Peroxide H2O2 will ultimately break down into H2O and O2. The lone O atom is unstable and quickly becomes O2.
Another change can be rapid Oxidation (Burning). This radically changes the material.
What else can I help you with?
What expands when it is heated?
When heated, most substances expand due to the increase in kinetic energy of their atoms or molecules. This leads to an increase in the average distance between the particles, causing the substance to expand.
What happens to the volume of most substances as they are heated?
Most substances expand as they are heated because the increase in temperature causes the individual particles to move faster and spread out, resulting in an overall increase in volume. This expansion is due to the increased kinetic energy of the particles.
Why do the densities of most substances decrease with an increase in temperature?
This happens because the mass of the rod stays the same, but its volume increases. The increase in the volume of matter withincreasing temperature is called expansion. When cooled down, mostmatter decreases in volume and increases in density.
When most objects are heated?
Expand
What happens when the temperature of a substance decreases significantly A. Most substances will expand. B. Most substances will gain atoms. C. Most substances will contract. D. Most substances will d?
C. Most substances will contract. When the temperature of a substance decreases significantly, its particles lose kinetic energy, causing them to move closer together. This results in a decrease in volume, known as contraction.
What happens when most substances are heated?
All get very hot.
What happens to most substances when they are heated?
When substances are heated, typically their molecules gain energy and begin to move more rapidly. This increased movement can cause the substance to expand, change phase (from solid to liquid or gas), or even chemically react to form new substances. The specific changes depend on the substance's properties.
What expands when it is heated?
When heated, most substances expand due to the increase in kinetic energy of their atoms or molecules. This leads to an increase in the average distance between the particles, causing the substance to expand.
What happens to a solid when is heated?
A substance in the solid phase will typically expand when heated. Most substances when heated sufficiently will melt into a liquid, assuming that they do not combust or sublimate.
What expands when its heated?
Most substances expand when heated.
What do most substances like the liquid in a thermometer do when they are heated?
expand
How does the density of most substances change when they are heated?
Most substances expand and become less dense when heated because the increased thermal energy causes the molecules to move farther apart, which decreases the density. However, there are exceptions such as water, which becomes denser when heated from 0°C to 4°C due to its unique behavior when transitioning from a liquid to a solid.
What happens when evaporation occurs?
When heated up, water molecules (and most molecules in general) will speed up, and start moving quickly. When they reach a certain heat, they turn into gas. It's quite simple.
What happens to the volume of most substances as they are heated?
Most substances expand as they are heated because the increase in temperature causes the individual particles to move faster and spread out, resulting in an overall increase in volume. This expansion is due to the increased kinetic energy of the particles.
Why do the densities of most substance decrease with temperature?
Most substances expand as they are heated, causing the atoms or molecules to spread out and the volume to increase. Since the mass remains constant, the density (mass per unit volume) decreases as the volume increases with temperature.
What happens to the volume of most substances when they get hot?
It expands
Why do the densities of most substances decrease with an increase in temperature?
This happens because the mass of the rod stays the same, but its volume increases. The increase in the volume of matter withincreasing temperature is called expansion. When cooled down, mostmatter decreases in volume and increases in density.
