Answer:
Clouds generally form within the troposphere.
Explanation:
A cloud is a mass of water droplets, ice crystals or both at the same time, which remains in suspension in the atmosphere, and whose formation is due to the condensation of water vapor in the sky.
Clouds form when the air is saturated and can no longer contain water vapor, this can happen in two ways:
1. The amount of water in the air has increased.
2. The air cools to its dew point.
Clouds generally form within the troposphere.
A. The temperature of a substance goes down as heat is added.
B. During a phase change, the temperature of a substance does not
change.
C. If heat is added to a substance, the temperature always
increases
D. The temperature of a substance is constant during a phase
change.
Answer:
Answer A is wrong
Explanation:
because the temperature increases as soon as the temperature increases
Hope it helps you
Statements A and C are both false. Adding heat to a substance typically causes its temperature to rise, but this is not the case during a phase change. During a phase change, a substance's temperature remains constant because the added heat goes into the phase transition.
In physics, understanding how heat energy affects the temperature and phase state of a substance is crucial. Out of the provided statements, option A and C are false.
A. The temperature of a substance goes down as heat is added - This is false. By default, adding heat to a substance causes its temperature to rise, unless a phase change is in progress.
C. If heat is added to a substance, the temperature always increases - This statement is also false. While it's true in many situations, during a phase change (for example, when ice is melting or water is boiling), adding heat does not raise the temperature. Instead, the energy goes into changing the phase of the substance.
Meanwhile, option B and D are correct. B. During a phase change, the temperature of a substance does not change, and D. The temperature of a substance is constant during a phase change - Both are true statements that reflect the same fact: during a phase change, any added heat goes into the phase transition, not into raising the temperature.
