What factors affect the amount of heat produced?

Answer 1

Factors which affect the amount of energy needed to change the temperature of a substance are:

1) the amount (mass) of the substance

2) what temperature change is required (from what temperature to what temperature)

3) the specific heat of the substance, which is "the number of calories required to raise the temperature of 1 gram of the substance by 1 degree Centigrade"

4) the ambient temperature of the surroundings where this change is to be carried out

Answer 2

factors that affect how heat i absorbed include: where the heat is absorbed; In the air, molecules absorb most of the heat. Another factor is what is absorbing the heat; An oven mitt will absorb heat from the pan you are handling. And how much heat is being used or put out. A good amount of heat can penetrate an oven mitt, and large asteroids can burn through the ground because of the velocity and heat they carry.

Answer 3

Many factors influence temperature.

1) Temperature of a living body (plant or animal) is affected by environmental factors = air temp, RELATIVE humidity, internal energy source (e.g. food eaten), evaporation, contact with a conductive object of a different temperature, degree and type of movement are main ones for living things, I think.

2) Temperature of inanimate objects is a function of surrounding environment (temp, humidity, airflow, insolation or other external application of energy), internal activity (such as crystallization in process, radioactivity, chemical reaction).

3) TEMPERATURE, per se, is not an absolute characteristic (as mass or weight is, in everyday terms). It is a highly variable aspect of the flow of energy.

4) In a cosmological sense or scale, temp is a measurement of the absolute flow of energy in the universe. This is called entropy. Entropy is universally considered to be in a constant state of growth, in which the temperature of everything gradually trends towards absolute zero, which is negative 459.67 degrees Fahrenheit = 0 degrees Kelvin, as best as general science knows at this point. There is no doubt that cosmologists and physicists will develop more knowledge about such things over time, for now (20th & early 21st Centuries) this is what we know, and what we can reliably use in life as we know it.

Answer 4

Heat capacity is the ratio of the heat added or subtracted to an object to the resulting temperature change. Translation, rotation, and a combination of the two types of energy in vibration of atoms represent the degrees of freedom of motion which classically contribute to the heat capacity of matter.

Answer 5

As we know all electrical appliances are made of semiconductor devices which yield high amount of heat due to charge collisions in them. These charges accumulate to form as increment in heat dissipation. Also the voltage regulators which are used in regulating the voltage for the different ICs also liberate large amount of heat.

Another Answer

Let's get the terminology correct. There's no such thing as 'heat energy'; the correct term is 'internal energy' ('heat' simply describes the transfer of energy from a warmer body to a cooler body). The internal energy of a body (or, as you put it the 'heat energy generated'), is the difference between the work done (I2Rt) on the appliance and the heat transferred away from the appliance. This is summarised by the equation:

W - Q = m c (T1 - T2)

...where: W = work; Q = heat transfer; m = mass of appliance; c = specific heat capacity; (T1-T2) = change in temperature.

Answer 6

1. mass of an object

2. temperature of the object

3. amount of energy, specific heat

Answer 7

The factors affect the amount of heat produced can vary greatly. One factor that affects heat is the temperature of the environment.

Answer 8

the UV rays. I think.
