How much heat is needed to raise the temperature of a 5.0 gram block of aluminum from 22.0° c to 37.0° c?

To solve for the heat needed, use the equation:

Q= m x c x ΔT

Where:

Q is the heat needed

m is the mass of (block of) aluminum

c is the specific heat capacity of aluminum

ΔT is the change in temperature

Solution:

Q= m x c x ΔT

Q= (5g) x (0.902 J/g•°C) x (37.0°C - 22.0°C)

Q= (5g) x (0.902 J/g•°C) x (15°C)

Q= 67.65 J

overcharge is the right answer system

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.
