Answer: hope it will help you

Explanation:

he correct answer is:  0.9 cal  

Explanation:

The formula for the specific heat (s) is:

s = (q)/(m * ΔT) --- (1)

Where

s = Specific heat = 0.09 cal/g°C

m = mass (make sure it is in GRAMS) = 70g

ΔT = Change in temperature = 21° - 20° = 1°

q = Heat Energy = ?

Plug in the values in the Equation (1):

(1) => q = (70*1*0.09) = 6.3 cal

Answer:

Explanation:

Explanation: Mass of copper block (m)=70gm

                     Temparature (t) = 20°C

                      Heat required (Q) = ?

                      Specific heat of copper (c) = 0.09cal/g°C

                      Q = m.t.c

                          =70×0.09×20

                        = 126 Cal.
