The temperature of an object is directly proportional to the amount of heat energy it contains. And changing the temperature of an object, therefore, means changing the heat energy it contains. But the temperature is also dependant on the object's mass, and a property of the material called the specific heat. Specific heat is the the heat per unit mass that corresponds to a unit temperature (e.g. 1 degree) for the particular material. For example, liquid water's specific heat is 1 calorie per gram per degree celcius, or 1 cal/g∙°C.
More about water:
- For every 0.57 btu's* heat added to one pound of ice will raise the temperature of the ice 1°F at atmospheric pressure, up to 32°F.
- For every 144 btus added to ice at 32°F and 1 atmosphere, one pound of ice will melt with no change in temperature.
- For every btu of heat added to 1 pound of water the temperature will rise 1°F at atmospheric pressure, from 32°F to 212°F
- For every 972.3 btus of heat added to water at 212°F and atmospheric pressure, 1 pound of water will be evaporated.
- For every 0.47 btus of heat added to 1 pound of steam at atmospheric pressure the temperature will rise 1°F.
* For metric units: 1 gram = 0.00220462 pounds, 252 calories = 1 btu, and 1°C = 1.8°F, with temperature of fusion at 0°C and temperature of evaporation at 100°C
More generally, if we consider Q as heat energy in an object, then ΔQ is a change in that energy, and take the mass of a substance as m and the specific heat (at constant volume) as Cv and t2 and t1 are final and initial temperatures, then we get the following equation:-
ΔQ=m∙Cv∙(t2-t1)

What is the relationship between energy transfer and temperature change?
Energy transfer and temperature change are directly related. When energy is transferred to a substance, such as through heating, the temperature of the substance increases. The amount of temperature change depends on the amount of energy transferred and the specific heat capacity of the substance.
What is the relationship between the Joule temperature and the energy transfer in a thermodynamic system?
The Joule temperature is a measure of how the energy of a thermodynamic system changes with temperature. It quantifies the relationship between temperature and energy transfer in the system.
What is the relationship between thermal kinetic energy and the temperature of a substance?
The relationship between thermal kinetic energy and the temperature of a substance is that as the thermal kinetic energy of the particles in a substance increases, the temperature of the substance also increases. This is because temperature is a measure of the average kinetic energy of the particles in a substance.
What is the relationship between internal energy and temperature in an isothermal process?
In an isothermal process, the internal energy of a system remains constant because the temperature does not change. This means that the relationship between internal energy and temperature is that they are directly proportional in an isothermal process.
What is the relationship between temperature and the type of energy, whether it is thermal, kinetic, or potential energy?
The relationship between temperature and the type of energy is that temperature is directly related to the amount of thermal and kinetic energy in a system. As temperature increases, so does the thermal and kinetic energy of the particles in the system. Potential energy, on the other hand, is not directly affected by temperature.

What is the relationship between the energy of a system and its temperature when the system is at 3/2 kb t?
The relationship between the energy of a system and its temperature when the system is at 3/2 kb t is that the average energy of the system is directly proportional to the temperature. This relationship is described by the equipartition theorem in statistical mechanics.
What is the relationship between air enthalpy and the efficiency of a heating and cooling system?
The relationship between air enthalpy and the efficiency of a heating and cooling system is that the enthalpy of the air affects the amount of energy needed to heat or cool it. Higher enthalpy levels require more energy to change the temperature of the air, which can impact the efficiency of the system. In general, a heating and cooling system will be more efficient when working with air at lower enthalpy levels.
What is the relationship between temperature and the activation energy on a graph?
On a graph, the relationship between temperature and activation energy is typically shown as an inverse relationship. As temperature increases, the activation energy required for a reaction decreases. This is because higher temperatures provide more energy to molecules, making it easier for them to overcome the activation energy barrier and react.
What is the relationship between temperature and the thermal potential or kinetic energy of a system?
The relationship between temperature and thermal energy in a system is that as temperature increases, the thermal energy of the system also increases. This is because temperature is a measure of the average kinetic energy of the particles in a system. So, higher temperature means higher kinetic energy and vice versa.
How is the relationship between temperature and kinetic energy explained in physics?
In physics, the relationship between temperature and kinetic energy is explained by the fact that temperature is a measure of the average kinetic energy of the particles in a substance. As temperature increases, the particles move faster and have more kinetic energy. Conversely, as temperature decreases, the particles move slower and have less kinetic energy.
How does temperature differ from thermal energy and what is the relationship between the two?
Temperature is a measure of the average kinetic energy of the particles in a substance, while thermal energy is the total kinetic energy of all the particles in a substance. The relationship between temperature and thermal energy is that an increase in temperature usually leads to an increase in thermal energy, as the particles move faster and have more energy.
