If the specific heat of copper is 0.711 j/g•°c, how much copper would it take if the heat given off is 54.85 calories and the temperature change is 205°c.

m = 1574.02 g

Explanation:

Given data:

Specific heat capacity of copper = 0.711 j/g.°C

Mass of copper = ?

Calories given off = 54.85 Cal (54.85 × 4184 = 229492.4 j)

Temperature changes = 205°C

Solution:

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

Q = m.c. ΔT

m =  Q / c.ΔT

m = 229492.4 j / 0.711 j/g.°C.205°C

m = 229492.4 j / 145.8 j/g

m = 1574.02 g

i believe the answer is c. "baking" is the gerund, while "baking blueberry muffins" would be the gerund phrase. hope this ! : )

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
