During a phase change what happens to the temperature?

Answers

Answer 1
Answer: During a phase change the substance or objects temperature increases or decreases depending on which way they go, Solid to liquid to gas needs added heat which makes it an endothermic reaction. Gas to liquid to solid loses heat energy to slow down its particles this is an exothermic reaction.
Answer 2
Answer: The temperature either rises or falls during a state change. 
Ex. 
Melting from ice to water~ the temperature is rising.

OR

Ex. 
From a gas to a liquid~ the temperature is falling.

When a warm air mass and cold air mass come together, like a warm front and cold front, a typical outcome is rain. What explains why rain forms in this situation? A. The cold air causes the moisture in the warm air to condense and precipitate as rain.
B. The cold air is moving faster than the warm air, which causes rain.
C. Because the cold air is denser, it causes rain.
D. The two air masses neutralize each other, which results in clouds that produce rain.

Answers

Answer:

A,when the two air masses meet,the cold air cools the block if warm air,causing it to condense and form stratus clouds( blankets of blank clouds that form when air rises slowly e.g. a warm air mass meets a cold one). Eventually when the cloud becomes saturated precipitation falls from them(precipitation is moisture in any form that falls from the atmosphere).

Whats is the definition of Parallel Circuit

Answers

A parallel circuit is one in which there's a place where the flow of current
can split up and follow different paths.

An example might be: 
Two lamps plugged into the same outlet and both turned on.

Current that comes out of the outlet splits up, and parts of it flow
through each lamp.
No . of devices when connected parallely or when they don't depend on each other to conduct electricity makes a parallel circuit.
