  1. By using less water per wash cycle

  2. By recycling water for multiple wash cycles

  3. By reducing the need for detergents and fabric softeners

  4. By generating hot water for other laundry appliances
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Water-efficient washing machines are designed to minimize water usage per wash cycle, typically using less than half the water compared to conventional models.

Multiple choice

What was the primary function of the Roman aqueducts?

  1. Irrigation

  2. Transportation

  3. Water supply

  4. Sewage disposal
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Roman aqueducts were primarily used to transport water from distant sources to cities and towns for public use.

Multiple choice

What is the function of a dam in a hydropower plant?

  1. To store water

  2. To generate electricity

  3. To control the flow of water

  4. To provide irrigation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The dam is used to store water and create a reservoir. The water in the reservoir is then released through a turbine to generate electricity.

Multiple choice

What is the function of a spillway in a hydropower plant?

  1. To control the flow of water

  2. To generate electricity

  3. To store water

  4. To provide irrigation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The spillway is used to control the flow of water in the reservoir. It prevents the reservoir from overflowing and causing flooding downstream.

Multiple choice

What is the function of a penstock in a hydropower plant?

  1. To carry water from the reservoir to the turbine

  2. To generate electricity

  3. To store water

  4. To provide irrigation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The penstock is a pipe that carries water from the reservoir to the turbine. The water in the penstock is under high pressure, which helps to turn the turbine.

Multiple choice

What is the function of a draft tube in a hydropower plant?

  1. To carry water away from the turbine

  2. To generate electricity

  3. To store water

  4. To provide irrigation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The draft tube is a pipe that carries water away from the turbine. The water in the draft tube is at low pressure, which helps to turn the turbine.

Multiple choice

What is the function of a governor in a hydropower plant?

  1. To control the speed of the turbine

  2. To generate electricity

  3. To store water

  4. To provide irrigation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The governor is a device that controls the speed of the turbine. It ensures that the turbine operates at a constant speed, even when the load on the plant changes.
