When a woman stands with two feet on a scale, the scale reads 280 N. When she lifts one foot, the scale reads A. less than 280 N. B. more than 280 N. C. 280 N.

Answers

Answer 1

Answer:

The right answer is 280 N.

What is total weight on the scale?

When a woman stands with two feet on a scale, the scale reads 280 N and when she lifts one foot, the scale also reads 280 N because the weight of the other leg also comes on the one leg.

First, the whole weight of the body depends on two feet but when the second feet is lifted, the weight of the whole body including the lifted feet comes on the single feed so we can conclude that the right answer is 280 N

During a phase change what happens to the temperature?

Answers

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.

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.
