Q1) Define in a brief format a) Heat, b) Temperature and c) Thermometer
Answers
Answer:
a.Simply heat is the sum of kinetic energy of atoms or molecules. In thermodynamics, heat means energy which is moved between two things when one of them is hotter than the other. Adding heat to something increases its temperature, but heat is not the same as temperature.
b. Temperature is a measure of how hot or cold something is; specifically, a measure of the average kinetic energy of the particles in an object, which is a type of energy associated with motion. ... The terms hot and cold are not very scientific terms.
c. A thermometer is an instrument for measuring or showing temperature (how hot or cold something is). One type of thermometer is a narrow, concealed glass tube containing mercury or alcohol which extends along the tube as it expands. Another type is a digital thermometer, which uses electronics to measure temperature.
