Temperature and Temperature Scales Review

Convert 32°F to Celsius.

• 0°C

• 10°C

• 5°C

• -5°C

What is the formula to convert Celsius to Kelvin?

• K = C + 273.15

• K = C - 273.15

• K = C * 273.15

• K = C / 273.15

What is absolute zero?

• The temperature at which water freezes.

• The theoretical lowest temperature possible, 0 K, where all molecular motion stops.

• The temperature at which all gases become liquids.

• The temperature at which ice melts.

Define Kelvin scale.

• A temperature scale where 0 K is absolute zero, and water freezes at 273.15 K and boils at 373.15 K.

• A temperature scale that measures temperature in degrees Celsius only.

• A scale used to measure the brightness of stars in astronomy.

• A temperature scale that is only used in cooking.

Define Celsius scale.

• A temperature scale where 0°C is the freezing point and 100°C is the boiling point of water.

• A temperature scale that measures absolute zero at 0 Kelvin.

• A temperature scale where 0°F is the freezing point and 100°F is the boiling point of water.

• A temperature scale that is only used in scientific laboratories.

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

• 90°C

• 100°C

• 110°C

• 95°C

What is the significance of the Kelvin scale in scientific research?

• It provides an absolute reference point for temperature measurements.

• It is used exclusively for measuring pressure.

• It is the only scale that can measure negative temperatures.

• It is primarily used in cooking and food science.

What is the freezing point of water in the Celsius scale?

• -10°C

• 0°C

• 5°C

• 100°C

Which temperature scale is typically not used for scientific purposes?

• Celsius

• Kelvin

• Fahrenheit

• Rankine

Explain why Fahrenheit is less commonly used in scientific contexts.

• Fahrenheit is based on absolute zero, making it suitable for scientific calculations.

• Fahrenheit is less precise and not based on absolute zero, making it less suitable for scientific calculations.

• Fahrenheit is more widely used in scientific contexts due to its precision.

• Fahrenheit is easier to convert to Celsius, making it preferable in scientific contexts.
