I Really need help With CHEMISTRY !! How do I do this? 1. Find the amount of heat (Q) needed to raise the temperature of 5.00 g of a substance from 20.0 to 30.0 degrees Celsius, if the specific heat of the substance is 2.01J/g℃

2. A metal with a specific heat of 0.780 J/g℃ requires 45.0 J of heat to raise the temperature by two degrees Celsius. What is the mass of the metal?

1: 100.5 J

2: 28.8 g

I  found the answers online ;-;"

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.
