What factors influence how much the temperature of an object will increase or decrease?
The amount of matter or mass and the temperature are the two factors that determine the thermal energy of an object.
How does an object increase or decrease in temperature?
When the temperature of an object increases, the average kinetic energy of its particles increases. When the average kinetic energy of its particles increases, the object’s thermal energy increases. Therefore, the thermal energy of an object increases as its temperature increases. 2.
What factors does temperature depend on?
1. Mass of object 2. Temperature of the object 3. Phase (solid, liquid, gas) of the object Thermal Energy Page 8 Thermal Expansion An increase in the volume of a material due to a temperature increase.
Which 3 factors determine what the specific heat of an object will be?
This quantity is known as the specific heat capacity (or simply, the specific heat), which is the heat capacity per unit mass of a material. Experiments show that the transferred heat depends on three factors: (1) The change in temperature, (2) the mass of the system, and (3) the substance and phase of the substance.
How does temperature affect object?
Heat, once absorbed as energy, contributes to the overall internal energy of the object. One form of this internal energy is kinetic energy; the particles begin to move faster, resulting in a greater kinetic energy. This more vigorous motion of particles is reflected by a temperature increase.
What happens to the temperature of an object if it is heated?
What happens to an object being heated? When an object is heated, its particles move more vigorously and its internal energy increases. Unless the object changes state (eg melts or boils), its temperature will increase.
What determines how much something will change the temperature?
The heat Q transferred to cause a temperature change depends on the magnitude of the temperature change, the mass of the system, and the substance and phase involved. (a) The amount of heat transferred is directly proportional to the temperature change.
How much heat is required to raise the temperature?
The specific heat capacity of a substance is the quantity of heat needed to raise the temperature of a unit quantity of the substance by one degree. Calling the amount of heat added Q, which will cause a change in temperature ∆T to a weight of substance W, at a specific heat of material Cp, then Q = w x Cp x ∆T.
