Temperature & Heat
Notes for Chapter 6
Summary for chapter 6 is below:
We need to know what is the definition of heat.
Heat is the measure of hotness/coldness of an object/environment
the SI unit is Kelvin.
Heat can be transfered through 3 ways
conduction
when two object are in contact, one object with higher temperature will give out energy to the object with a lower temperature.
e.g. when two persons shake hands
convection
it happens in fluids (gas / liquid)
e.g. magma from volcano
radiation
the object no need to in contact
e.g. the fried chicken is kept warm using light in the mamak stall
