Question

How much heat is required to change temperature of 2g of water from 34°C to 68°C? (Water has a specific heat of 4.18)
a) 852.7 joules
b) 284.2 joules
c) 2 joules
d) -284.2 joules

Answer 1

Answer: B

Explanation:

To find the amount of heat required, you would use q=mcΔT.

$q=2g(4.18J/g°C)(68-34°C)$

q=284.2 J

*Please ignore the capital A in the equation. I can't find a way to type in the degree sign into the equation without the A appearing.
