she used asensor to measure the temperature of the ice
i. what temperature will the sensor show when the ice is melting?
ii. briefly describe how melting of the ice occurs?
iii. if she is freezing pure water from liquid to solid what temperature does she expect this to occur at?
C)explain how evaporation occurs?
D)why can a liquid evaporate whitout the addition of any heat ( in other words why can it occur in a glass of water sitting at room temperature?​

Answer 1

Answer:

(i) 0°C

(ii) When the ice cube gains heat from the surroundings it starts to melt. We say that heat gain can change the state of matter.

(iii) 0°C

(C) When water gains enough heat it boils and changes into steam. Evaporation occurs.

D) The room temperature never remains constant. Change in temperature can affect the state of matter.
