The internal energy of a material is determined by its temperature, pressure, and specific heat capacity. The internal energy is the sum of the kinetic and potential energies of the particles within the material. Temperature affects the kinetic energy, pressure affects the potential energy, and specific heat capacity determines how much energy is needed to change the temperature of the material.
What else can I help you with?
Matter can absorb and reflect light?
Yes, matter can absorb light when it interacts with it, causing the energy of the light to be converted into internal energy within the material. Matter also reflects light when the surface of the material does not absorb the light's energy but instead bounces it back. The color of the material is determined by which wavelengths of light are absorbed and which are reflected.
What is the total energy of particles in a material called?
The total energy of particles in a material is called internal energy. It includes the kinetic and potential energies of the particles due to their motion and interactions within the material.
What determines a system's thermal energy?
The thermal energy of a system is determined by the temperature of the system and the amount of material present.
The internal energy of an ideal gas depends on?
The internal energy of an ideal gas depends only on its temperature. This is because an ideal gas does not have attractive or repulsive forces between its particles, and thus its internal energy is determined solely by the kinetic energy of its particles.
What happens to the light waves during absorption?
During absorption, light waves transfer their energy to the absorbing material, causing the electrons in the material to move to higher energy levels. This leads to an increase in the internal energy of the absorbing material.

What factors determine the rate at which energy is absorbed by a material?
The rate at which energy is absorbed by a material is determined by factors such as the material's specific heat capacity, density, and thermal conductivity. Additionally, the intensity and duration of the energy source, as well as the material's surface area and temperature, can also influence the rate of energy absorption.
What 2 factors affect elastic potential energy?
The two factors that affect elastic potential energy are the amount of stretch or compression of the elastic material and the stiffness of the material, determined by its spring constant.
What is the tendency for a material to oppose the electron flow and change electrical energy in to thermal energy and light?
The tendency for a material to oppose the flow of electrons and convert electrical energy into thermal energy and light is known as resistance. This property is determined by the material's resistivity and is quantified in ohms (Ω). The higher the resistance of a material, the more it will convert electrical energy into heat and light.
Difference between heat energy and internal thermal energy?
Heat is thermal energy in transit. This process is carried out naturally between two material systems which are at different temperatures.Thermal energy is the energy of a body(or material system) has due to the movement of its particles.In other words, "bodies do not have heat, they have thermal energy".CommentThe term, 'thermal energy' is obsolete; it is now called 'internal energy'.
What would happen to any material if the temperature changes from 12 Celsius to 56 Celsius?
Its internal energy increses
