A system transfers 20 kJ of heat to the surroundings write the value of q (heat) or both the system and the surrounding.
Please answer correctly with steps
Answers
Answer:q(system)=-20kJ
q(surrounding)=+20kJ
Explanation:
System of Heat in Thermodynmics
Explanation:
1. System :The study of effect of temperature, pressure on the part of the universe is called as system.
2. Surrounding: The remaining portion of the universe , excluding the universe is known as surrounding
Types of system
1. Open system - Exchange of both matter and energy with surrounding
2. Closed system- Exchange of energy only
3. Isolated system- Neither exchange of matter and energy
First law of thermodynmics:
The total energy of the universe remains constant, only transformation from one form to other happens only.
- Heat is a form of energy which exchanged betwwen system and surrounding.it is denoted by q
Sign of q;
Heat given by the system to surrounding = +q
Heat is absorbed by the system = -q
Here's your answer :
q ( system) = -20 kJ
q ( surrounding) = +20 kJ
