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.
Is the thermal energy that flows from one substance to another when the substances differ in temperature?
Yes, it is.
Why do the densities of most substances derease with temperature?
resistance of only electrolytes and semiconductors decrease wid temp.This is so coz in these substance due to increase in temp, the no. of ions and electrolytes in conduction band increases .Thats why resistance decreases.
How long does heat flow to one substance into another?
Until the two substances reach the same temperature.
What happens to the temperature of a substance when you prevent gain or loss of thermal energy?
If you define "thermal energy" as heat, and the "substance" is not affected by any energy that increases or decreases its temperature, by definition, nothing will happen to its temperature. If the substance reacts to electromagnetism, light or other radiation, it may increase or decrease its temperature, depending on the nature of the substance and its reaction to those energies. Note: See Discussion question.
Which substance decreases in solubility as the temperature rises?
Endothermic substances.
When a substance melts The temperature of the substance increases?
it decreases.
When a substance melts the temperature of the substance?
it decreases.
When a substance is melting the temperature of the substance what?
it decreases.
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.
What decreases the rate at which a substance melts?
decreasing the temperature
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.
If the resistance of a substance decreases as its temperature increases it is said to have what type of temperature co-efficient?
copper
What is the effect of temperature change to the amount of heat content of the substance?
The effect of temperature change to the amount of heat content of the substance is called heat transfer. As heat increases, the temperature decreases.
What happens to enthalpy when temperature is decreased?
the atoms (or molecules) within the substance move slower, as temperature decreases.
What is the temperature of a substance that has changed from a liquid to a gas?
If all substances are at equilibrium, the temperature is the boiling point, at the prevailing pressure, of the substance that has changed from liquid to gas.
