Question

The specific heat of copper is about 0.400 yg C. How much heat is needed to change the temperature of a 30.0-gram sample of copper from

20.0°C to 50.0°
A. 240 j
B. 480 j
C. 720 j
D. 1000 j


Someone please help me answer this ASAP

Answer 1

Q = 360 Joules

Step-by-step explanation:

specific heat of copper = 0.400 J/g° C

mass of copper = 30 g

initial temperature = 20.0°C

final temperature = 50.0°C

Using the formula:

Q = mcΔT

where;

Q = Heat Energy

`Q = m*c * (T_2-T_1)`

Q = (30 × 0.400)(50-20)

Q = 360 Joules
