Chem Lovers, today we learn about heat and temperature. Also, try to solve general chemistry questions related to heat & temp. like, what is heat? what is temperature? what is difference between heat & temp. If you want to learn in Hindi then, read our Heat, Temp. in Hindi ताप और तापमान

What is Heat?

The exchange of energy due to difference in temperature is called heat. But as a noun we can say that, it is the quality of being hot or high temperature and to understand easily we can say that feeling of hot or warm is heat.

Heat

The exchange of energy due to difference in temperature is called heat. We may also explain as, heat is the form of the energy that is moved between two substances at different temperatures. Means if two substances are in contact and one has 200K temperature and other have 100K temperature then the direction of energy flow is from the substance at the higher temperature to the substance of lower temperature. Means in above case heat flows from substance having 200K temperature to substance having 100K temperature.
Heat is a form of energy so heat is measured in units of energy, commonly calories or joules.

 

What is Temperature?

Temperature is the quantity of hotness or coldness of any substance. Simply we can say that Temperature is the measurement of how much an object is hot or cold.

Temperature

Temperature is the quantity of hotness or coldness. Also in scientific way, temperature is explained as the average kinetic energy per molecule of a substance. Temperature (Temp, T) and Heat are two different terms and have different meanings so don’t get confuse between them.  Heat is energy while temperature is not energy. Heat is measured in Joules while temperature is measured in Celsius (C), Fahrenheit (F) or Kelvin (K). Symbol used for heat is Q while symbol used for temperature is T. SI unit of heat is Joule while SI unit of temperature is Kelvin.

Heat and Temperature Difference

 
Up to now, we learn what is heat and what is temperature. Now we learn, about heat and temperature difference. So, below are the some differences between temperature and heat.
 
Heat is the flow of energy from hot object to cold object while temperature is the measurement of how much an object is hot or cold. Heat is energy while temperature is not energy. Heat is measured in Joules while temperature is measured in Celsius (C), Fahrenheit (F) or Kelvin (K). Symbol used for heat is Q while symbol used for temperature is T. SI unit of heat is Joule while SI unit of temperature is Kelvin.
