Calculate 50g 25.0c to 95.000<br>O.897 J / (g.c)​
chubhunter [2.5K]

Answer:

Q = 3139.5 j

Explanation:

Given data:

Mass = 50 g

Initial temperature = 25°C

Final temperature = 95°C

Specific heat capacity = 0.897 j/g.°C

Heat absorbed = ?

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

ΔT = T2 - T1

ΔT =  95°C - 25°C

ΔT = 70°C

Q = m.c. ΔT

Q = 50 g× 0.897 J/g.°C ×70°C

Q = 3139.5 j

Which layer of Earth is responsible for the movement of tectonic plates?
vesna_86 [32]
Convection currents in the mantle are what causes the movement of tectonic plates. As the extremely hot molten material from the mantle rises toward the crust, it cools enough to become denser and sink back into the hotter area of the mantle.
