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 8
A block of iron at 50°C is placed in a container of water at 30°C. After some time, both reach 35°C. What is this final state called?
A cup of hot tea is left in a room at 25°C. What will happen to the temperature of the tea over time?
A metal block at 80°C is placed in water at 20°C. If they reach thermal equilibrium at 30°C, which object lost heat?
A scientist places a thermometer in a beaker of water. After a few minutes, the thermometer reads 25°C. What does this indicate about the thermometer and the water?
Describe a real-life example of thermal equilibrium.
Describe what happens to the temperature of ice water as it sits in a room at 25°C.
Describe what happens when a thermometer is placed in a liquid.
Explain the importance of the Zeroth Law of Thermodynamics in measuring temperature.
Explain why a metal spoon feels colder than a wooden spoon at room temperature, even though both are in thermal equilibrium with the room.
Explain why a thermometer does not immediately show the temperature of a substance when first placed in it.
Explain why a thermometer must be allowed to sit in a substance for a while before reading the temperature.
If a hot metal rod is placed in cold water, what will happen over time?
If a hot object and a cold object are placed together in an insulated container, what will eventually happen?
If object A is at 40°C and object B is at 40°C, and they are placed in contact, what will happen?
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 the temperatures of A and C?
If two objects are in thermal equilibrium with a third object, what can you conclude about the two objects?
What is thermal equilibrium?
