Which of the following is a statement of the first law of thermodynamics?

Energy cannot be created or destroyed.

Heat always flows from a hot object to a cold object.

Entropy of a system tends to decrease over time.

Pressure and volume are inversely proportional at constant temperature.

What is absolute zero in the Celsius scale?

0°C

−273.15°C

100°C

−459.67°C

What is the formula to convert temperature from Fahrenheit (F) to Celsius (°C)?

C = (F - 32) / 5

C = (F - 32) / 9

C = (F + 32) / 5

C = (F + 32) / 9

What is the SI unit of temperature?

Kelvin (K)

Celsius (°C)

Fahrenheit (°F)

Rankine (°R)

Which law of thermodynamics states that energy cannot be created or destroyed?

Zeroth law

First law

Second law

Third law

What is the formula for converting temperature from Kelvin to Celsius?

C = K + 273.15

C = K - 273.15

C = (K * 9/5) + 32

C = (K - 32) * 5/9

What law states that the pressure of a given mass of an ideal gas is inversely proportional to its volume at a constant temperature?

Boyle's law

Charles's law

Gay-Lussac's law

Dalton's law

Which of the following temperature scales does not have negative temperatures?

Rankine

Which law of thermodynamics states that the total entropy of an isolated system can never decrease over time?

Zeroth law

First law

Second law

Third law

0 K

100 K

273.15 K

373.15 K

#15

What is the relationship between Celsius and Fahrenheit scales?

C = (F - 32) / 9

C = (F - 32) / 5

F = (C * 9/5) + 32

F = (C * 5/9) + 32

#16
