Quiz about Flow of Energy and Flow of Heat Energy

Question 1

What might cause the food to not cook all the way through?

Accepted Answer

Not enough energy reaches the center of the food.

Answer

The energy cooks the outside of the food, and then the food begins to lose heat instead of cooking further

Answer

Energy flows into the food too quickly and is lost before the inside is cooked

Answer

The food conducts energy , so the energy passes through the food without cooking it

Question 2

A roller coaster car requires an input of energy from an electric motor to reach the top of the first hill. Which statement describes the transformation of energy involved in this process?

Accepted Answer

Electrical energy is transformed into mechanical energy

Answer

Mechanical energy is transformed into electrical energy

Answer

No energy transformation occurs

Answer

Electrical energy is transformed into chemical energy

Question 3

The Noria's of Hama are known for creaking loudly as the turn. Which statement about a Noria is correct?

Accepted Answer

Some kinetic energy of the Noria is transformed into sound energy

Answer

some kinetic energy of the Noria is transformed into light energy

Answer

The kinetic energy of the Noria does not change

Answer

The Noria does not have any input or output of energy

Question 4

Accepted Answer

Option B is correct

Accepted Answer

Option D is correct

Answer

A.

Answer

C.

Question 5

How might using a pizza stone instead of a pan affect how the pizza cooks?

Accepted Answer

The stone transfers energy slowly, so the crust cooks evenly

Answer

The stone absorbs energy, keeping the crust cooler than the pizza toppings.

Answer

The stone gets hotter than the rest of the oven, so the pizza cooks faster

Question 6

How does the gravitational potential energy of he water change as it approaches the top of the wheel?

Accepted Answer

its gravitational potential energy increases

Answer

Its gravitational potential energy does not change

Answer

its gravitational potential energy decreases

Question 7

How is Convection transferred?

Accepted Answer

Option B is correct

Answer

A.

Answer

C.

Question 8

When a meteoroid strikes Earth, mechanical energy is transformed into which of these forms of energy?

Accepted Answer

thermal energy and sound energy

Answer

Sound energy and electrical energy

Answer

chemical energy and sound energy

Answer

thermal energy and chemical energy

Question 9

Pizza restaurants often use large ovens lined with bricks. These ovens remain very hot, even through only a small fire is kept burning in the oven. Why might this be?

Accepted Answer

The bricks absorb thermal energy from the fire and stay hot because the heat flow back into the oven from the bricks slowly

Answer

Because the bricks are reds, keeping the fire hot

Answer

The bricks absorb the heat the makes the oven hotter

Question 10

Energy flow through a system that consists of the stove, the pan, the boliling water, and the air around these objects. Which of the following statements describe a direction that energy is moving in this system?

Accepted Answer

The stove to the pan and the pan to the water

Answer

The pan to the stove and the stove to the pan

Answer

The water to the pan and the pan to the water

Answer

The pan to the stove and the water to the pan

Question 11

Paddle boats are boats that are propelled by a paddle wheel using similar mechanics as a water wheel. A water wheel is propelled by flowing water. A paddle boat can be operated using human power, a steam engine, or solar power. Describe the energy transfers and transformation that takes place with in the paddle wheel system.

Accepted Answer

Human power is the mechanical energy that is the input into the paddle wheel

Accepted Answer

The transfer of energy is to the water.

Answer

Solar power is the input to the paddle wheel

Answer

Human power is the transfer of kinetic energy to the paddle boat

Question 12

Suppose you had a glass that was partially filled with water. Which of the following statements describe ways that you could raise the thermal energy of the glass of water?

Accepted Answer

Add water of the same temperature to the glass and warm the glass of water using a microwave

Answer

Add water of same temperature to the glass and remove water from the glass

Answer

Remove water from the glass and warm the glass of water using a microwave

Answer

Warm the glass of water using a microwave and Cool the glass of water using a refrigerator

Question 13

A student use a thermometer to measure the temperature at three places and recorded the data in a table. Which statements represent conclusions that you can support with these data? Select all that apply.

Accepted Answer

Energy has been transferred from the street to the air above that street.

Accepted Answer

The street surface has absorbed more radiant thermal energy than the sidewalk.

Answer

The temperature of the sidewalk the is the same as the temperature of the street.

Answer

Energy has been transferred from the lawn to the street and sidewalk through conduction.

Question 14

How is Conduction transferred?

Accepted Answer

Heat transfer through physical contact

Answer

Heat transfer through fluids or air

Answer

Heat transfer through electromagnetic waves/rays
