Heat is the total energy of molecular motion in a substance; temperature is a measure of the average energy of molecular motion in a substance. Heat energy depends on the speed of the particles, the number of particles (the size or mass), and the type of particles in an object. Temperature does not depend on the size or type of object. For example, the temperature of a small cup of water might be the same as the temperature of a large tub of water, but the tub of water has more heat because it has more water and thus more total thermal energy.

What happens when matter at a higher temperature touches matter at a lower temperature?
The colder matter absorbs the heat (thermal energy) from the hotter matter. Heat continues to "flow" until all of the matters is at about the same temperature. This is a fundamental law of thermodynamics; heat travels from where it's hotter to where it's colder.
Does pressure rise when heat rises?
Heat and temperature are two different terms. Heat is the cause and temperature is the effect. So when the temperature increases then the pressure increases provided the volume remains constant. This is what we call part of Charle's law.
How does a down sleeping bag keep you warm?
It insulates the heat of your body temperature in the bag.
Does thermometer measure heat or temperature?
Different thermometers make use of different physical properties, that change with temperature - for example, volume, electrical resistance, and others. The basic household thermometer simply has a liquid - previously mercury, nowadays usually colored alcohol - that expands when it is heated.
What happens when air temperature exceeds body temperature?
When air temperature exceeds body temperature, the only avenue for heat loss is via sweating. This is because bi-directional heating occurs via convection and radiation. However, the cooling power of sweating has long been known (Bladgen 1775a, 1775b). Therefore the degree in which core temperature would change depends on firstly how much air temperature exceeds body temperature and secondly the water vapour pressure of the environment.
Can two body at same temperature have different heat?
Yes. Heat is energy temperature is not, E1 =k1T and E2 = k2T the temperatures are the same but the heat is different because K1 is different from k2.
Is temperature different than heat?
Yes, quite different. . . . .Temperature is used to measure heat.
Can heat transfer from one object to with the same temperature?
This is not possible. Heat always move from a body of high temperature to a body of low temperature.
How is temperature diffrent from heat?
Heat is the cause and temperature is the effect. Heat is energy but temperature is outcome of storage of such heat energy in a body. If same amount of heat is given to the same mass of water and aluminium, then temperature will be more in aluminium but less in water. This is similar to the collecting air in different containers. Air is equivalent to heat and pressure created is equivalent to temperature.
Why heat gained and heat loss?
Since heat flows from high temperature region to low temperature region so when a hotter body comes in contect with colder body then hotter body loses heat to colder body until both have same temperature.
Why is heat different from temperature?
temperature can be cold
What is temperature and heat?
Heat is the energy transferred from one body to another as the result of a difference in temperature. Heat flows from a hotter body to a colder body when the two bodies are brought together. This transfer of energy results in an increase in the temperature of the colder body and a decrease in the temperature of the hotter body. Temperature is a measure of the average energy of the molecules of a body. It is expressed in terms of any of several scales, such as Fahrenheit, Celsius, or Kelvin.
How is heat different from temperature and thermal energy?
It is heat which is measured by a temperature scale.
What measures body's heat?
The body temperature is measured by a thermometer, the instrument to measure heat contents of objects is called a calorimeter. Don't confuse heat with temperature.
Differences between heat and temperature?
heat is a energy and temperature is a measurement . (of how concentrated it is)
Is temperature and heat the same thing or are they different?
they are different. temperature is the movement of particles. heat is the movement of temperature from place to place. temperature are the moving particles, heat is the movement of those particles from a place to a place.
What instrument measures body heat?
The body temperature is measured by a thermometer, the instrument to measure heat contents of objects is called a calorimeter. Don't confuse heat with temperature.
