Thank you so much both of you. This was really helpful for such a non-physics person like me. God bless you two!

That makes a lot more sense now :) 240 ÷ 95 = 2.526315789 Not quite sure how to round this...

Right. So 2 minutes = 120 s 2000 x 120 = 240000 J How do I find the mass now?

I believe it'll be 2000 W x 2.0 minutes = 4000 J Do I need to convert it into seconds first?

Q. Thermal energy is supplied to a melting solid at a constant rate of 2000 W. Calculate the mass of the solid changed to liquid in 2.0 minutes. Assume that the specific latent heat of fusion of the solid is 95 000 J kg-1 and that heat exchange with the surroundings may be neglected. I was...
