Heat and Temperature Puzzles
Test your knowledge of heat, temperature, and different temperature scales with these puzzles! Click the buttons to reveal hints and answers.
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.
