Answer:
2) motion of molecules
Explanation:
heat is a form of energy, molecules with more energy 'vibrate' more
The word that goes on to the gap is "cells"
Hope it helped!
Stars Like the Sun. When the core runs out of hydrogen fuel, it will contract under the weight of gravity. ... The upper layers will expand and eject material that will collect around the dying star to form a planetary nebula. Finally, the core will cool into a white dwarf and then eventually into a black dwarf.
Answer: D is right
Explanation: It seems both waves have same wavelength.
Because speed = wavelength · frequency (v = λf) and
f = v/λ, so frequency is same. Because period T = 1/ frequency, also periods are same. Wave Y has higher amplidude and its energy is greater.
Answer:
This is the specific heat capacity
Explanation:
The specific heat capacity of water is the quantity of heat energy needed to raise the temperature of 1 g of water by 1 degree.it is due to the aggregation of hydrogen bonding holding water molecules together.
Therefore,large quantity of heat energy is needed to be supplied to raise the temperature of water.
This is an advantage for earth temperature because a significant rise in the earth temperature,would not affect the earth because the ocean would have absorbed the heat.Therefore regulating the earth temperature within the narrow limits
However,during summer little heat is released by the ocean and this cools the earth,this is because the specific heat capacity of the ocean is higher than that of the land,thus as the ocean warms up slowly its warms the earth.
