Thermal Equilibrium
Physics ⇒ Heat and Thermodynamics
Thermal Equilibrium starts at 8 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Thermal Equilibrium.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 9
A 100 g piece of metal at 80°C is placed in 200 g of water at 20°C. If the final temperature is 25°C, which substance absorbed more heat?
A block of ice at 0°C is placed in a room at 25°C. What will happen to the temperature of the ice over time?
A cup of tea at 80°C is placed in a room at 25°C. What will be the final temperature of the tea after a long time?
A metal block at 50°C is placed in water at 20°C. If the final temperature is 25°C, which object had a greater mass or specific heat capacity?
A metal spoon is placed in a cup of hot coffee. After some time, the spoon and the coffee are at the same temperature. What is this state called?
A scientist places a thermometer in a beaker of water. After a few minutes, the thermometer reads 22°C. What does this indicate about the thermometer and the water?
Describe a real-life situation where thermal equilibrium is reached.
Describe what happens to the temperature of two objects when they are brought into contact and allowed to reach thermal equilibrium.
Describe what would happen if a thermometer is not allowed to reach thermal equilibrium with the object being measured.
Explain what happens to the net heat flow between two objects as they approach thermal equilibrium.
Explain why a thermometer must be in thermal equilibrium with the object whose temperature it is measuring.
Explain why heat does not flow between two objects at the same temperature.
Explain why the concept of thermal equilibrium is important in designing thermometers.
If a hot metal rod is placed in cold water, what will happen over time?
If a thermometer reads 30°C when placed in a liquid, what can you say about the temperature of the liquid?
If object A is in thermal equilibrium with object B, and object B is in thermal equilibrium with object C, what can you say about objects A and C?
If two objects are in thermal equilibrium with a third object, what can you say about their temperatures?
The Zeroth Law of Thermodynamics is important for defining which physical quantity?
What is meant by thermal equilibrium?
Which law states: 'If two systems are each in thermal equilibrium with a third system, then they are in thermal equilibrium with each other'?
