What term describes how much energy it takes to change the temperature of the substance?
specific heat capacity
What best describes the enthalpy of formation of a substance?
The energy change that happens when a substance forms from its elements (APEX)
Is temperature a form of energy?
Temperature is not a form of energy, but a measurement of energy (specifically, heat energy). You can't add temperature to a substance, because every substance already has a temperature, whether it be at -50o C or 900o C. However, you can add heat to change the temperature.
Why does the amount of water affect time it takes to boil?
The basic formula which describes the energy required to raise the temperature of a substance is ΔE=mcΔθ. where: ΔE = Difference in energy m = mass of the substance c = specific heat capacity of the substance Δθ = change in thermodynamic temperature without any calculation, it is clear that if the change in temperature is the same (i.e. from room temperature to boiling point); and the specific heat capacity is the same; the more of the substance that is being boiled; the more energy is required. If the device which is boiling the substance is at a constant power, whether it be a burner or a kettle, the more energy required to boil the substance, the more time it will take to boil so long as the power is held constant.
Why does temperature no change during energy phase change?
During a phase change, the heat transferred to a substance is used to break intermolecular forces (latent heat), and thus the temperature of the substance does not change. The opposite also occurs: heat is transferred from a substance during a phase change without a decrease in temperature as intermolecular bonds form.
What term describes how much energy it takes to change the temperature of the substance?
specific heat capacity
What best describes temperature of substance?
average kinetic energy
What substances make up temperature?
None. Temperature is a term/concept that affects any substance and any atom. Temperature describes the kinetic energy (dependend on their speed) that the atoms your substance is made of have. Dependend on your substance you need different amount of heat energy to change the temperature. This property is called heat capacity.
How does a substance 's temperature change when the average kinetic energy of it's particle increases?
As the average kinetic energy of a substance increases, the temperature will increase.
What best describes the enthalpy of formation of a substance?
The energy change that happens when a substance forms from its elements (APEX)
Does the energy content of a substance change during a phase change?
Yes, but not the temperature.
Is temperature change chemical?
No. Temperature is not a change of any sort. It is a measure of the average kinetic energy of the particles in a substance.
Is temperature a form of energy?
Temperature is not a form of energy, but a measurement of energy (specifically, heat energy). You can't add temperature to a substance, because every substance already has a temperature, whether it be at -50o C or 900o C. However, you can add heat to change the temperature.
What describes the behavior of a substance during a phase change?
It either absorbs or releases energy
Why does temperature stay the same during a phase change?
The temperature, in Physics, means the measure of Kinetic Energy in a substance. When a substance is either heated or cooled, Kinetic Energy is either being added to taken away from the substance. When the amount of KE in the substance changes, the temperature change. However, when the substance is changing its state, because all the KE change in the substance is being used up to change the state, the temperature will not change. When the substance is changing state, the KE can be measured by calculating the heat of fusion and heat of vaporization.
Why does evaporation require that heat energy be added to a substance?
Heat is energy the substance needs to change it's state of matter (the more energy a substance has the higher it's 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.
