Answer:
b) Asthenosphere
Explanation:
The Earths crust is broken into plates. These plates float on the Asthenosphere. This is observed in the diagram.
First , ocean currents are actually big convection currents moving heat around. Second, ocean currents moves food and nutrients from deeper water in a process called upwelling.
Answer:
harder
heavier objects resist change more than lighter objects.
Answer: a. (Q), (T), (E)
b. (Q), (T), (E), (W)
Explanation: <u>Thermal</u> <u>Energy</u> and Temperature are closely related: when the temperature rises causing atoms or molecules to move, thermal energy is produced. Thermal energy is the energy within the system.
<u>Mechanical</u> <u>Work</u> is the amount of energy transferred due to an applied force.
<u>Chemical</u> <u>Energy</u> is the energy contained in the bonds of chemical structures of the molecules released when a chemical reaction happens.
Given the explanations, let's analyse the situations:
a. For an ice cube to be melting, it has to be absorbing heat, which means its thermal energy is changing and, consequently, so does its temperature;
b. First, the gas inside the cylinder reaches a thermal equilibrium, which means its thermal energy and temperature changed. Since there were exchange of heat to reach the equilibrium, the gas absorbed or gave off heat. After the equilibrium, when the piston starts to be moved, the energy of the pressure is transferred to the gas, so mechanical work had been done.
"<em>The prime mover of a hybrid vehicle is its main energy source, which generally is one of gasoline, diesel, or fuel cells. The electric motor is one of the most important components in a hybrid vehicle.</em>"
