Answer:
is 3 and 2
Explanation: the firth one is 3 and the 2
The amount of heat required is B) 150 J
Explanation:
The amount of heat energy required to increase the temperature of a substance is given by the equation:
where:
m is the mass of the substance
C is the specific heat capacity of the substance
is the change in temperature of the substance
For the sample of copper in this problem, we have:
m = 25 g (mass)
C = 0.39 J/gºC (specific heat capacity of copper)
(change in temperature)
Substituting, we find:
So, the closest answer is B) 150 J.

Answer:
waves
Explanation:
There are three major ways in which heat or thermal energy is transferred namely: conduction, convection and radiation. Please find the description of each below;
- Conduction is the method of heat transfer which involves a physical contact between the substances involved.
- Convection, on the contrary, occurs via a liquid medium
- RADIATION is a method of heat transfer which involves neither physical contact or liquid medium (matter) but occurs through WAVES e.g electromagnetic waves. For example, the sun transfers heat to the Earth via RADIATION.
