Answer:
The amount of energy needed to change the temperature of a certain supstance is given in the equation:
Q = c • m • ∆T
-Q is the amount of energy in Joules
-c is the specific heat capacity, a constant value for each supstance that shows amount of energy needed to raise the temperature of 1 g of a supstance by 1 K. Its unis is J/g•K (for lead, c=0.129J/g•K)
-m is the mass of the given supstance in grams
-∆T is the change in the temperature in Kelvins. In this case it's 350-295=55K
So, now, let's calculate:
Q = 0.129J/g•K • 500g • 55K
Q = 3,547.5 J
Rounded to the nearest whole number that is 3,548 Joules
