Question

I underestand what the labels are, I need help with the second and third rows. Thanks in advance!

A is ice
B is melting
C is liquid
D is evaporization
E is gas

d. Examine the heating curve for water below. Answer each question and complete the table to review your understanding of heating curves. (1 point) 200 T 150 100 50 50 0 10 20 3040 50 60 70 Time (min) Which state or phase change ispotential energy represented? Does kinetic or Which specific heat capacity or latent heat change? is used to find the heat?

Explanation / Answer

First go through theory

Heat energy of a body is comprised of two energies:-

i) kinetic energy of molecules of that vary with temperature

ii) potential energy due to intermolecular space between molecules that changes when phase or state of matter changes.

Therefore

A ,C, E- temperature change hence kinetic energy changes

B ,D - phase changes hence Potential energy changes

For third row

Specific heat is related to temperature change and latent heat is related to pahase change.

A - specific heat of ice

B - latent heat of melting/ fusion ( as ice melts to water)

C - specific heat of water

D - latent heat of vapourisation ( as as water evapourattes into steam)

E - specific heat of steam

Also for first row change ice to solid or

Change liquid to water and gas to steam
