chapter 1:- Heat Synopsis Videos TQs Bits short notes 1.Heat Heat is a form of energy which flows from the body at higher temperature to the body that has lower temperature. (from hot body to cold body.) Formula :- Q=ms∆t Where Q= heat (absorbed or lost) m = mass ∆t = temperature difference Units :- 1. joule (J) in S.I system) 2. calorie(cal) (in C.G.S system) 3. I cal = 4.186 joules. 5. Calorie: The amount of heat required to raise the temperature of 1 gram of water by 1 ° C is called calorie. 2.Temperature (T) 1. The degree of hotness or coldness is called temperature. 2. It depends on the average kinetic energy of the molecules of a system. 3. Units:- a. kelvin(K) (in S.I system) b. degree celsius(in C.G.S system) 4. Normal temperature of a healthy human is 98.6° F or 37° C o...
