When a substance melts The temperature of the substance increases?
it decreases.
When a substance melts the temperature of the substance?
it decreases.
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.
Molecules in a substance slow down when a substance is?
Molecules in a substance slow down when a substance is cooled. Temperature is the measure of average kinetic energy of particles. Kinetic energy is the energy of motion. So when temperature decreases, the average kinetic energy decreases, so the energy of motion decreases, and the molecule slows down.
Does the precautionary demand for money decreases as the interest rate decreases?
Decreases when the inflation rate increases
What Explain what happens to the average kinetic energy, thermal energy, and temperature of a substance when the particles in the substance slow down.?
The particles in a substance slow down when the average kinetic energy of the particles decreases. As the average kinetic energy decreases, the internal energy decreases, and so the thermal energy decreases. As the thermal energy of the substance decreases, the temperature decreases.
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 does a substance absorb when it melts or boils?
Heat
When a rock melts what substance does it become?
Lava.
How does the density change from solid to liquid to gas?
The density generally decreases as a substance transitions from solid to liquid to gas. In the solid state, particles are tightly packed resulting in higher density. When the substance melts into a liquid, the particles become less ordered and the density decreases. As the liquid is further heated to form a gas, the particles are further apart, leading to the lowest density.
What substance melts at -38.9 degree c?
Mercury melts at approximately -38.9 degrees Celsius.
The rate at which temperature decreases with increasing altitude is known as?
The rate at which temperature decreases with increasing altitude is known as the lapse rate.
