Wrong Answer:
Percentage: %
- A. Heat always flows from a system at lower temperature to a system at higher temperature.
- B. The mass of a system is altered when it is heated or cooled.
- C. For any exchange of heat, the heat gained by the cold system is greater than the heat lost by the hot system.
- D. Heat gained = Heat lost.
Remarks:
Explanation:
For any exchange of heat, the heat gained by the cold system is equal to heat lost by the hot system. This is known as the law of conservation of energy and is represented by the equation Heat gained = Heat lost.
- A. K = (C + 32) × 5/9
- B. K = C - 273
- C. K = C + 273
- D. K = (C × 9/5) + 32
Remarks:
Explanation:
The relationship between Celsius and Kelvin temperature scales is given by the equation K = C + 273, where K is the temperature in Kelvin and C is the temperature in Celsius. This means that the temperature difference of 1°C is equal to that of 1K.
- A. Temperature
- B. Pressure
- C. Volume
- D. Density
Remarks:
Explanation:
Temperature is the property which determines whether a body is in equilibrium or not with the surroundings.
- A. The hot body gets colder and the cold body gets hotter
- B. The hot body gets hotter and the cold body gets colder
- C. The hot body and the cold body remain at the same temperature
- D. The hot body and the cold body exchange volumes
Remarks:
Explanation:
There will be a transfer of heat energy from the hot body to the cold body until a thermal equilibrium is established between them.
- A. Temperature measured in relation to absolute zero
- B. Temperature measured in relation to room temperature
- C. Temperature measured in relation to boiling point of water
- D. Temperature measured in relation to melting point of ice
Remarks:
Explanation:
The temperature measured in relation to absolute zero using the kelvin scale is known as absolute scale temperature.
- A. Conduction
- B. Convection
- C. Radiation
- D. Expansion
Remarks:
Explanation:
Convection is a process of heat transfer where heat is transferred through the movement of a fluid, such as air or water. This occurs when a heated fluid expands and rises, while a cooler fluid contracts and sinks, creating a circular motion that transfers heat.
- A. A balloon expanding when heated
- B. A puddle evaporating in the sun
- C. A metal rod increasing in length when heated
- D. Water freezing and expanding in a container
Remarks:
Explanation:
Linear expansion refers to the increase or decrease in the length of an object due to changes in temperature. A metal rod increasing in length when heated is an example of linear expansion.
- A. Steel
- B. Glass
- C. Copper
- D. Aluminum
Remarks:
Explanation:
Explanation: Glass has a higher coefficient of linear expansion compared to other materials, which makes it more susceptible to thermal expansion.
- A. The temperature of the substance rises.
- B. The substance may change its state from solid to liquid or from liquid to gas.
- C. The substance will contract when heated.
- D. The substance will expand when heated.
Remarks:
Explanation:
When heat energy is supplied to a substance, the temperature of the substance rises and it may change its state from solid to liquid or from liquid to gas. Additionally, the substance will expand when heated. The substance will not contract when heated.
- A. The amount of heat energy required to rise the temperature of 1 gram of water through 1°C.
- B. The amount of heat energy required to rise the temperature of 1 kilogram of water through 1°C.
- C. The amount of heat energy required to boil 1 gram of water.
- D. The amount of heat energy required to freeze 1 gram of water.
Remarks:
Explanation:
A calorie is a unit of energy defined as the amount of heat energy required to raise the temperature of 1 gram of water by 1 degree Celsius.
