Question

What is the approximate boiling point of the substance represented by the complete heating curve below?

Answer 1

30°C
40°C
50°C
100°C

Answer 2

What do u think ?

Answer 3

i really don't know :'(

Answer 4

Let's understand this with the help of an example, say water.

Answer 5

kk

Answer 6

Suppose u have an ice cube at -30 degrees. Now u started heating it, the temp will rise rapidly and reach to 0 degrees.

Answer 7

At zero degrees temperature will not increase further until the whole ice cube is melt.

Answer 8

alright

Answer 9

After the ice has cmpltly melted into water, temperature will rise again upto 100 degrees and then stop rising until the whole water has turned into gaseous state.

Answer 10

graph for water will be something like this.

Answer 11

Now can u select the correct option ?

Answer 12

remember that the lines that are on an incline are used to represent the heating of the substance and the flat lines are used to represent the breaking of the bonds during the transition of the phases for that substance so lets say that we know the solids are the lowest energy the first phase transition will be melting and the second will be boiling now try to find the corresponding temperature.

Answer 13

Umm idk why my computer doesn't show that you posted anything. So I am using my phone and it shows that you said something but I don't know what so hold on for my computer to stop lagging

Answer 14

Whew! Finally! I think it is 50 degrees!

Answer 15

Answer 17
