What else can I help you with?
Does the temperature of ice increase or decrease when it melts?
The temperature of ice increases when it melts.
When a substance melts the temperature of the substance?
it decreases.
When a substance is heated its temperature increases. What other change might be observed?
Ordinarily when a substance is heated it expands. In some cases it melts. In some cases it vaporizes/evaporates.
What happens to viscosity as temperature increases?
As the temperature rises, the viscosity, meaning a substance's resistance to flow decreases because a liquid based substance melts, and flows more.Viscosity decreases as temperature increases.
How does a substance 's temperature change when the average kinetic energy of it's particle increases?
As the average kinetic energy of the particles in a substance increases, the temperature of the substance also increases. This is because temperature is a measure of the average kinetic energy of the particles in a substance. So, when the average kinetic energy increases, the temperature increases as well.
What decreases the rate at which a substance melts?
decreasing the temperature
How is the themal energy of a substance?
The thermal energy of a substance is a measure of the total kinetic energy of its particles. It is directly proportional to the temperature of the substance. As the temperature increases, the thermal energy of the substance also increases.
What happens to the temperature of water after an ice cube fully melts?
IT slowly increases back to room temperature
When does a substance changes from a solid to a liquid?
A substance changes from a solid to a liquid at the substance's melting point. This is a different temperature for every substance. For example, water (ice) melts at 0oC, whereas gold melts at 1,064oC.
What is the relationship between thermal kinetic energy and the temperature of a substance?
The relationship between thermal kinetic energy and the temperature of a substance is that as the thermal kinetic energy of the particles in a substance increases, the temperature of the substance also increases. This is because temperature is a measure of the average kinetic energy of the particles in a substance.
Why does density decrease as temperature increases?
As temperature increases, the particles in a substance move faster and spread out more, causing the substance to expand and decrease in density.
Does the temperature change if the average kinetic energy of a substance changes?
When Ave KE increases temperature increases.
