What is the substances specific heat?
The amount of heat required to increase the temperature of the substance to 1 degree greater than that of the initial temperature of the body!
What is the SI base unit for the amount of substance?
The SI base unit for the amount of substance is the mole (mol).
What happens to the solubility of gases with the increase in temperature?
solubility generally increases with a temperature increase
Why does the amount of denitration increase at high temperatures?
- the speed of reaction increase with increasing temperature - the actual efficiency increase with increasing temperature
Study Island Which substance would require the largest amount of energy to increase the temperature of 20 grams by 1.0 K?
hydrogen!!! Hydrogen14.30 Jg-1K-1
What does it mean to say that a material has a high or low capacity?
The specific heat capacity of a substance is the amount of energy required to increase the temperature of a said substance 1o K. The capacity is measured in kilojoules divided by kilogram time degrees Kelvin (kJ/Kg k). So, if the specific heat capacity of a substance is high, it requires a very large amount of energy to increase the temperature, and if it has a low specific heat capacity, the required energy will be lower.
What is the amount of energy required to raise the temperature of 1 kilograms of a substance by 1 kelvin is called?
Specific heat is the amount of heat needed to melt one kilogram of a substance...heat of fusion
What is the substances specific heat?
The amount of heat required to increase the temperature of the substance to 1 degree greater than that of the initial temperature of the body!
What happens to particles as the temperature increases?
As the temperature of a substance increases, its molecules move faster and therefore take up more space. This generally causes a substance to increase in volume when heated.
Is Temperature is a measure of the amount of heat stored in a substance?
Temperature is not a measure of the amount of heat stored in a substance. It is the measure of the kinetic energy of the molecules of a substance.
Is temperature an element?
No, temperature is the amount of thermal energy in a given amount of a substance.
What is substances specific heat?
The amount of heat required to increase the temperature of the substance to 1 degree greater than that of the initial temperature of the body!
Does temperature affect the amount of substance dissolved in a saturated solution?
Yes temperature affects the amount of substance dissolved in a saturated solution.
What happens to the density of a given substance if you increase the amount of substance that you have?
No change: Density is a property of the substance (physical property), which is not changed by the amount of substance.
The amount of heat needed to melt one kilogram of a substance?
heat of fusion
What is a latent heat energy levels?
Latent heat- the amount of heat required by a system/ substance to change phase. It's also heat absorbed or radiated during a change of phase at a constant temperature and pressure.
What is the amount of heat needed to increase the temperature of a certain mass of a substance by 1 degree Celsius?
The heat capacity of a substance is the amount of heat required to raise the temperature of a defined amount of pure substances by one degree (Celsius or Kelvin). The calorie was defined so that the heat capacity of water was equal to one.
