How much heat, in joules, is required to warm a metal disc from 19 °C to 33 °C? The
zalisa [80]

Answer:

Q = 96.6 j

Explanation:

Given data:

Heat required = ?

Initial temperature = 19°C

Final temperature = 33°C

Mass of disc = 3.0 g

Specific heat capacity = 2.3 J/g.°C

Solution:

Specific heat capacity:

It is the amount of heat required to raise the temperature of one gram of substance by one degree.

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 = 33°C - 19°C

ΔT = 14°C

Q = 3.0 g×2.3 J/g.°C × 14°C

Q = 96.6 j

I will mark brainlist In what layer are convection currents found?
Pavel [41]

Answer:

Convention currents are found in the asthenosphere part present in the mantle of the Earth.

Explanation:

The Mantle is the middle layer of the earth surface extending up to 2900 kilometers.

Beneath the Mantle lies the core which contains molten rocks and materials called magma.

The materials are highly radioactive and immensely heated. These highly hot condition creates pressure on the middle layer (Mantle).

As a result, large convention currents are generated excessively
