Puzzle 1: What is the key difference between heat and temperature?

One measures energy; the other measures intensity.

Heat is the energy transferred between objects, while temperature measures the average kinetic energy of particles.

Puzzle 2: What is the SI unit of heat?

It’s related to energy.

The SI unit of heat is the joule (J).

Puzzle 3: Name the three temperature scales commonly used.

One is Kelvin; can you recall the others?

The three temperature scales are Kelvin (K), Celsius (°C), and Fahrenheit (°F).

Puzzle 4: How do you convert from Celsius to Kelvin?

It involves adding a constant value.

To convert from Celsius to Kelvin, add 273.15: K = °C + 273.15.

Puzzle 5: What temperature is the same on both the Celsius and Fahrenheit scales?

It’s below freezing point.

The temperature is -40 degrees, which is the same on both Celsius and Fahrenheit scales.

Puzzle 6: How do you convert from Fahrenheit to Celsius?

It involves subtraction and a fraction.

The formula is: °C = (°F - 32) \times \frac{5}{9}.

Puzzle 7: Why does a thermometer rise when placed in hot water?

It’s related to particle motion.

The heat causes the liquid particles in the thermometer to expand, causing the level to rise.

Puzzle 8: At what temperature does water boil on the Kelvin scale?

It’s the Celsius boiling point plus 273.15.

Water boils at 373.15 K.

Puzzle 9: What happens to the kinetic energy of particles as the temperature increases?

Temperature and energy are directly related.

The kinetic energy of particles increases as the temperature rises.

Puzzle 10: What is the freezing point of water on all three scales?

One scale starts at absolute zero.

The freezing point of water is 0°C, 32°F, and 273.15 K.
