What is used to find the specific heat capacity of a substance?
The equation for specific heat is: C = q/temp. change x mass. C is a substance's specific heat, which is a constant for every substance. q is its heat capacity in joules, temp. change is the change in temperature in degrees Celsius, and mass is in grams.
What is the name given to heat energy at melting point?
The heat energy required to change a substance between solid & liquid at constant temperature is called the "latent heat of fusion". If the change is from solid to liquid the substance gains this energy. If the change is from liquid to solid the substance gives up this energy. The exact amount of latent heat of fusion is different for different substances.
During thermal expansion what happens to the density of a substance?
Thermal expansion is the tendency of matter to change in volume in response to change in temperature. During thermal expansion, the density of a substance decreases as its volume increases. Volume is the space occupied by a body. So, when a substance expands on heating, it will occupy more space or will have more volume. But its mass does not change because the amount of matter contained in a body cannot change. Therefore, mass divided by increased volume gives a decreased density.
What is the amount of energy needed to raise the temperature of 1 kg of a substance 1C.?
A substance's molar specific heat capacity is the amount of energy required to raise one mole of that substance 1 degree Celsius.For water, this is exactly one calorie, assuming the state of the water does not change. Otherwise, it depends on the substance, and the substance's current temperature and state.for apex its latent
Can a physical change change what a substance is?
a physical change will only alter the appearance but will NOT change the substance to another substance =)
Does the energy content of a substance change during a phase change?
Yes, but not the temperature.
How does temperature relate to amount of energy present in a substance?
Higher temperature means greater energy content compared to a lower temperature. The energy required to change the temperature is proportional to the mass of the system, the specific heat capacity, and the temperature change.
What During a phase change the temperature of a substance .?
The temperature* remains unchanged. * The heat (energy) content changes.
What properties of a substance does not change when the amount of the substance changes 1 mass 2 volume 3 temperature?
temperature
What happen to the temperature of a substance during a phase change?
The temperature* remains unchanged. * The heat (energy) content changes.
What is specific heat a measure of?
The amount of energy it takes to change the temperature of a substance by a certain amount. How much energy it takes to heat a substance ~APEX
What are two physical properties that can that can vary when the substance with these physical properties that dose not change?
Temperature and amount of the substance do not change chemical properties.
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.
Do properties remain the same regardless of the amount of the substance?
Intensive properties remain the same with a change in the amount of a substance - for example: temperature and density Extensive properties do not remain the same with a change in the amount of a substance - for example: mass and volume
What is specific latent heat.?
It is the amount of energy required to change the state of 1kg of a substance with no change in temperature.
What is the amount of change in the thermal energy of a certain mass of a substance per degree of change in temperature?
That is called the specific heat.
If a substance is not at its melting or boiling point as the heat content of a sample of matter increases what happens?
As the heat content increases, the temperature of the substance will rise. However, if the substance is not at its melting or boiling point, it will not undergo a phase change. Instead, its temperature will continue to increase until it reaches its melting or boiling point, at which point a phase change will occur.
