Thermal energy is an example of kinetic energy , due to motion of particles .
Answer:
A.
1. when the butter was placed on the spoon it slowly started to boil then began to melt.
2.the order was to heat the bowl, let it boil, then place the butter in.
3.The heat got from the water to the butter by placing it on the spoon then physically moving it into the hot bowl.
4.objects that do not conduct heat are called insulators.
B.
1. When the ice cube got placed into the water it immediately melted.
2.the water from the ice cube to the warm water as soon as it got laced it immediately melted.
3. the heat flowed straight up which made the ice melt really fast.
TABLE A: when I placed the butter in it melted a little bit slower than the ice cube but it still melted very fast.
TABLE B: when I put the colored one in the color slowly dissolved and pushed the color to the middle and the cube melted.
TABLE C: room temp water:75 degrees
cold water:50
hot water:315 degrees
TABLE D: when I blew out the candle the flame went but the smoke started to rise up.
TABLE E: the small beaker heated up quicker and I observed that the less amount of mass the faster it will heat up.
TABLE F: the black piece of paper heated up quicker and I believe its because the darker color the more mount of heat is attracted.

Answer: The Senate provides advice and consent on presidential nominations.
According to the question; The output power is 0.643W.
<h3>What do you mean by power?</h3>
Power is the quantity of energy that is transported or transformed per unit of time in physics. The watt, which is equal to one joule per second in the International System of Units, is the unit of power. Power may also be referred to as activity in earlier writings. A scalar concept is a power.
According to the question:
Power, P₁ = 150W
Sound intensity level, β = 103db
Distance, d = 1.60m
The sound intensity level is β = 10log(I/I₀)
Reference intensity I₀ = 10⁻¹²
By solving, Intensity, I = 0.02w/m²
Power output P₀ = (4πd²) I
P₀ = 0.643W
