1

Which of the following states of matter exists at the lowest temperature?

71% Answer Correctly

liquid

gas

none of these

solid
Solution

Solids exist at a lower temperature than liquids which exist at a lower temperature than gases.

2

Heat is always transferred from __________ to __________ environments.

69% Answer Correctly

cooler, warmer

empty, dense

warmer, cooler

dense, empty
Solution

Heat is always transferred from warmer to cooler environments and conduction is the simplest way this transfer can occur. It is accomplished through direct contact between materials and materials like metals that transfer heat efficiently are called conductors while those that conduct heat poorly, such as plastic, are called insulators.

3

Materials like metals that transfer heat efficiently are called:

83% Answer Correctly

conductors

refractors

reflectors

insulators
Solution

Heat is always transferred from warmer to cooler environments and conduction is the simplest way this transfer can occur. It is accomplished through direct contact between materials and materials like metals that transfer heat efficiently are called conductors while those that conduct heat poorly, such as plastic, are called insulators.

4

In the water cycle, infiltration is most closely related to:

41% Answer Correctly

rivers

runoff

oceans

water table
Solution

The water then accumulates as runoff and eventually returns to bodies of water or is absorbed into the Earth (infiltration) and becomes part of the water table, an underground resevoir of fresh water.

5

Acceleration is the rate of change of velocity per unit of time. Which of these is the formula for acceleration?

59% Answer Correctly

\(\vec{a} = { \vec{v} \over t }\)

\(\vec{a} = { t \over \Delta \vec{v} }\)

\(\vec{a} = { \Delta \vec{v} \over t }\)

\(\vec{a} = \Delta \vec{v} t \)
Solution

Acceleration is the rate of change of velocity per unit of time. In physics, the delta symbol (\(\Delta\)) represents change so the formula for acceleration becomes  \(\vec{a} = { \Delta \vec{v} \over t }\)
