Answer:
Electric and heat
Explanation:
Forms of solar energy include electricity and heat
When solid melts, the temperature of the substances increases and the substance absorbs heat energy, converting the solid to a liquid.
Answer : The specific heat of substance is 
Explanation :
Formula used :

or,

where,
Q = heat needed = 4.90 kJ = 4900 J
m = mass of sample = 894.0 g
c = specific heat of substance = ?
= initial temperature = 
= final temperature = 
Now put all the given value in the above formula, we get:
![4900J=894.0g\times c\times [17.5-(-5.8)]^oC](https://tex.z-dn.net/?f=4900J%3D894.0g%5Ctimes%20c%5Ctimes%20%5B17.5-%28-5.8%29%5D%5EoC)

Therefore, the specific heat of substance is
