Activity ; Write the definition of the following words with examples. Number one is done for you . Start your definition like number one .

1. Freezing-is the temperature at which a liquid becomes a solid at normal atmospheric pressure.

Example- of freezing is when water turns into ice.

2. Vaporization-is the process of transition of a liquid into vapors when heat is provided to it.

Example- salt is recovered from sea-water by the process of vaporization

3. Condensation-is the process where water vapor becomes liquid.

Example- dew forming on grass in the early morning, eye glasses fogging up when you enter a warm building on a cold winter day, or water drops forming on a glass holding a cold drink on a hot summer day

4. Sublimation- conversion of a substance from the solid to the gaseous state without its becoming liquid.

Example- dry ice which is a frozen form of carbon dioxide..

5. Reverse sublimation- when a gas phase changes directly to a solid without becoming a liquid first.

i hope it's help you:)

answer: option c. i.e. electric current flowing “downhill” from the negative electrode to the positive electrode in a battery

explanation:

the water analogy to the circuits define the pipes (water flows) to the electric current. now, we know that the electric current flows from the positive terminal to the circuit (as shown in the diagram attached).

hence, option c is the correct answer.
