Answer:
sun, air, water, wind and ocean current
Explanation:
As sun is the major source of energy on earth, the earth gets heated due to solar energy, this creates convection currents in the Air and Water, the heating of these areas create wind and ocean currents due to difference in temperature and pressure.
Answer:
9/10hr
Explanation:
From the question given:
Carla was able to burn 250 calories by running for one-half (1/2)hr.
Therefore, Carla will burn 450calories by running for = (450x1/2) /250 = 225/250 = 9/10hr
Answer:
HF & CH3OH
Explanation:
Hydrogen bonds are formed as a consequence of the attractions between a partially positive hydrogen (δ+ hydrogen) atom of a molecule and a lone pair of another electronegative element, such as a nitrogen, oxygen or fluorine molecule of another molecule.
In the case of HF, the partially positive hydrogen atom makes a hydrogen bond with the lone pair of a fluorine atom of another HF molecule in its proximity.
In the case of CH3OH, the partially positive hydrogen atom (bound to Oxygen) makes a hydrogen bond with the lone pair of an oxygen atom of another CH3OH molecule in its proximity.

It is C. An increase of temperature results in an increase in kinetic energy of the molecules of the substance. For example, in a gas the molecules will move about faster.
