**“What is Heat and Temperature in Physics.”**After reading this article all reader easily understand all the questions.

**Question: –** What is the relative heat unit in SI method?

**Answer: –** In SI method the unit of relative heat is J / kg K.

**Question: – **What is the unit of thermodynamics in SI method?

**Answer: –** The thermodynamic unit in SI method is JUL / K or JUL / oC.

**Question: –** What will be the final temperature if you give 80 calories of heat in 1 gram of ice at 20oC temperature?

**Answer: –** 1 gram of ice at 0oC temperature is given 80 calories of heat. That is, the final temperature will be 0oC.

**Question: –** What is the relative heat of a liquid?

**Answer: –** The relative heat of water is highest.

**Question: –** What are two of the heat measurement scales?

**Answer: **The heat scales are two Celsius scale and Fahrenheit scale.

**Question: –** What is the relative heat of pure water?

**Answer: –** Relative heat of pure water in CGS and SI method is 1 cal / g oC and 42000 Jol / kg Kelvin respectively.

**Question: –** What is the amount of heat received by an object?

**Answer: –** The amount of heat received by an object = mass of the object x relative to the material element x increase the heat.

**Question: –** What are the constants of the Celsius scale of warmth?

**Answer: –** Celsius scale 0oC and upper-temperature 100oC on the Celsius scale of warmth.

**Question: –** What are the Fahrenheit scale constants?

**Answer: –** Fahrenheit scale is lower 32oF and higher is 212oF.

**Question: –** What is the primary heart of a thermometer?

**Answer: –** The interval between the upper constant of the thermometer and the lower constant is called the initial interval.

**Question: –** What is the initial interval of the Fahrenheit scale constants?

**Answer: –** The initial intervals of the Fahrenheit scale constants = upper coordinates – lower coordinates = 212oF – 32oF = 180oF.

**Question: –** What is the unit of heat in SI method?

**Answer: –** The unit of heat in the SI method is Jull.

**Question:-** When does the principle of calorimetry not apply?

**Answer: –** The principle of calorimetry does not apply if the heat exchanged between two objects or the heat energy is converted to chemical or any other energy during the exchange of heat between any two objects.

**Question:** On a medical thermometer, what is the scale of warming?

**Answer: –** Medical thermometers are usually on a Fahrenheit scale for warmth. However, at present, the Celsius scale has also been introduced in medical thermometers.

**Question: –** Which is less than 0oC and 0oF?

**Answer: –** 0oF is less than 0oC and 0oF.

**Question: –** What is the relative heat of iron 462 Jol/kg K?

Answer: – The relative heat of iron is 462 Jol/kg K implies that 46 kg of heat is needed to increase the heat of 1 kg of iron by 1K or 1oC.

**Question: –** 1 calorie = how many joules?

**Answer: –** 1 calorie = 4.2 Jul.

**Question: –** What is the temperature of a mercury thermometer?

**Answer: –** The temperature of the mercury thermometer is the propagation of mercury.

**Question: –** What is the mathematical form of calorimetry?

**Answer: –** The mathematical form of calorimetry is: heat received or discarded by an object = mass of object x relative heat x increase or decrease of heat. That is, H = mst.

**Question: –** In what way does heat from the sun take place on earth?

**Answer: –** The heat radiation from the sun takes place on earth.

**Question: –** What is the volume of copper at 42 J / K?

**Answer: –** One copper thermodynamic 42 Jol / K implies that 42 Jol heat will be required to increase the heat of that copper chunk to 1 K.

**Question:-** What are the different methods of conducting heat?

**Answer: – **Three methods of conducting heat, namely: transport, circulation and radiation.
