Temperature

What does a higher temperature indicate about the internal energy of a substance?

• It has constant internal energy.

• It has no internal energy.

• It has more internal energy.

• It has less internal energy.

Why is the Celsius scale considered convenient for scientific use?

• It uses arbitrary numbers.

• It is based on the freezing and boiling points of water.

• It has no historical significance.

• It is only used in the United States.

What is the freezing point of water on the Fahrenheit scale?

• 212 degrees Fahrenheit

• 32 degrees Fahrenheit

• 100 degrees Fahrenheit

• 0 degrees Fahrenheit

Which formula is used to convert Celsius to Fahrenheit?

• F = C + 32

• F = C / 1.8 + 32

• F = 1.8 * C + 32

• F = 32 - C

If the temperature is 10 degrees Celsius, what is it in Fahrenheit?

• 100 degrees Fahrenheit

• 68 degrees Fahrenheit

• 50 degrees Fahrenheit

• 32 degrees Fahrenheit

What is the boiling point of water on the Celsius scale?

• 212 degrees Celsius

• 100 degrees Celsius

• 32 degrees Celsius

• 0 degrees Celsius

What does 0 Kelvin theoretically represent?

• Maximum atomic motion

• No atomic motion

• Average atomic motion

• Infinite atomic motion

Why is the Kelvin scale important in chemistry?

• It relates to absolute zero and atomic motion.

• It is the only scale used in the United States.

• It defines the freezing point of water.

• It is used to measure weight.

How does temperature affect chemical reactions?

• Temperature has no effect on reactions.

• Higher temperatures slow down reactions.

• Higher temperatures generally speed up reactions.

• Lower temperatures speed up reactions.

What is the boiling point of water on the Fahrenheit scale?

• 32 degrees Fahrenheit
