Answer:
Different star constellations are visible from Earth at different seasons of the year.
Explanation:
The reason the fact that we can see different constellations in the sky during different seasons on earth is the most compelling reason we travel around the sun is because if the sun travelled around the earth, certain constellations would only be visible in certain places. You’d have to travel to see certain ones.
However, you don’t have to do that because we travel around the sun, therefore travelling around other stars too.
Answer:
Chemical energy
Explanation:
The energy held in the foods molecules a lunch pack is composed of is chemical energy.
They occur within food substances which originates from plants and animals as giant organic molecules.
- Since food is often derived from plants and animals.
- Plants produce their own food by producing macromolecules from simple inorganic substances in the environment.
- Animals takes up these food and build their own body through it.
- Plants and animal parts constitutes organic molecules in which chemical energy is duly stored.
- When the molecules are broken down, they released their chemical potential energy into heat energy.
At normal temperature,
specific heat of air = 1.006
concrete =0.96
water =4.187 (all are in KJ/KgK)
soil = 0.80
So, from <span>Q=mcDeltaT</span><span>
higher the specific heat lower the change in temperature for same quantity of heat supplied.
Therefore, water is the answer.</span>
