Chemistry What is Energy

According to the law of conservation of energy, in theory, a bouncy ball should never stop bouncing. However, we know that it eventually stops. Where does the energy go.

Both A and B

Energy is not conserved because it is like a waste product similar to smoke or sweat.

False

Energy is not stored in food. Food only gives you energy when you eat it.

False

In a discussion about stored energy, students agree that both beans and coal have stored energy. The teacher then asked, "Where did the energy come from that is stored in beans and coal?"

From the Sun's light

Energy is measured in units of

Joules

Sound energy is.

The energy caused by an object's vibrations

Jan takes off her glove and grabs a handful of snow. She holds it in her hand until it begins to melt. Read the information above. Which statement is TRUE?

Thermal energy flows from a material of higher temperature to one at lower temperature.

Kimi takes butter from the refrigerator and leaves it on the counter, where it softens. How does the thermal energy of the molecules of butter change while the butter sits on the counter?

Thermal energy increases.

Energy can be transformed (changed) from one form to another.

True

When energy is transformed from one kind to another, some of it may change to heat.

True

Objects can have kinetic energy, potential energy, or both. Energy can be in the form of motion. Energy can also be stored by objects in various ways, including position, chemical bonds, or physical state. Refer to the information above. What type of energy found in food is important for organisms?

chemical potential energy

The law of __________________ of energy states that energy cannot be created or destroyed

conservation

an takes off her glove and grabs a handful of snow. She holds it in her hand until it begins to melt. Read the information above. In which direction does thermal energy flow in this situation?

from Jan's hand to the snow

Energy is defined as the ability to do work, or the ability to cause change. Read the definition of energy given above. What type of energy is produced during the fusion process which takes place inside the Sun?

nuclear

The greater the average kinetic energy of the particles in a sample of matter,

the higher the temperature is.
