For these question you need to know these 2 formulas:
1)when it is mentioned about the temp. of a substance being changed from one temp. to another use this
Heat=ms(delta)T (s is the specific heat capacity)
2)when it is talked about phase change that is from ice to water or water to steam use this
Heat=mL (latent heat of fusion/vaporisation)
REMEMBER THAT S AND L HAVE DIFFERENT VALUES IN JOULE AND CALORIE.BE CAREFUL ABOUT THAT.Now use these formulas all above questions will be solved.

oh then why are u solving these?
hey why did u ask again?there is no other way for these questions
i know but i don’t know how to put the formulas into it
oh
u see the heading of tables
its written latent heat and specific heat as i wrote in my answer
m is given mass of substance
try just once its easy
sorry for all the bother, you don’t have to help me anymore. i just honestly don’t understand physics at all. and you seem to understand it. i just wanted the answers instead of the formulas bc i literally don’t know how to do it. This lesson was so hard for me to really get
oh m sorry.take a subject u love if possible for future
