• Sense of touch

On a day when the temperature reaches 50 °F, what is the temperature in degrees Celsius and in kelvins?

• 32.4°C and 305.55 K

• 18°C and 291.15 K

• 10°C and 283.15 K

Using the image, after quite some time are systems A and B in thermal equilibrium with each other?

• Yes

• No

• Not enough information

What is the apparent consequence of the temperature difference between two systems in thermal contact?

• Absolute temperature

• Energy transfer

• Thermal Equilibrium

How would you open a closed jar with a tight lid using water without breaking it?

• Hold it under flowing cold water.

• Hold it under flowing hot water.

• Let it float in contained water.

Which of the following relates temperature and heat?

• Heat and temperature are interchangeable.

• Heat flow always causes the temperature difference between systems.

• Heat is the energy in transit while the temperature is the quantified hotness or coldness of a system.
