Answer:

It Remains Constant

Explanation:

When the temperature over a matter remains constant, subsequently the kinetic energy among them is also constant, then there is a phase change.

The graph is a linear function given by the formula, which measures the heat necessary in the system:

Q=mcΔt

So it increases linearly in the same state. Remains constant when there's a change of state. According to the function above and the graph below.

<span>In a temperature time graph, the change of state at beginning is increasing rapidly like a exponential function. This is due to the fact that at the beginning the difference in temperature is much greater so the driving force is great. Towards the end the change is already very minimal or none because the difference is now almost zero</span>

Answer:

A.

Explanation:

Power is measured in Watts, and can we calculated by taking the work done in joules / the time in seconds. Thus, 1 Watt is 1 joule per 1 second (1 Watt = 1J/s)
