Question

1 What does the graph represent?

Answer 1

1. it represents the temperature of water over time
2.it goes up 50 degrees every 2 mins
3.they start to seperate
4. increses
5.because it is over a period of time
6.around 100
7.steam
8.100
9.time
10.temperature
11.it changes to gas
12. from solid to gas

Answer 2

1) Change of temperature with time

2) When temperature of water reaches a specific value, it's phase changes from cold to liquid to gas or vice-versa

3) Molecules of water breaks apart as temperature of water increases

4) As the time increases, time Increases

5) It is because there is a single thing (water) which is changing with respect to time.

6) At 100 C, water changes into gas

7) Vapor phase

8) Temperature of melting point of water is 0 C

9) "Time" is plotted on x-axis

10) "Temperature" is plotted on y-axis

11) It changes to Vapor phase at 100 C

12) "Phase Change of water"

Hope this helps!
