What is the mass of a piece of iron if it absorbs 5575 joules of heat and its specific heat capacity is 0.95 J/g°C? The initial
matrenka [14]

Answer:

The mass of iron piece = 586.84

Explanation:

Given,

Heat absorbed by iron piece(Q) = 5575 Joules.

specific heat capacity(Cp) = 0.95 J/g°C.

initial temperature(T₁) = 20.0°C

Final temperature(T₂) = 30.0°C

Mass of iron piece(m) = ?

The mass of iron piece can be calculated by using the formula ,

Q = (mass) (ΔT) (Cp)

Here, ΔT = T₂ - T₁ = 30°C - 20°C = 10°C

Substituting values we get,

5575 = (m)(10)(0.95)

Solving, we get,

m = 586.84 grams.

Therefore, mass of iron piece = 586.84 grams.

How do we think that Mars lost atmospheric gas?
grin007 [14]

the rocky planet was exposed to harsh and forceful solar winds, which blew the Martian atmosphere away.

Another option for thickening the atmosphere of Mars, and, in turn, raising the temperature of the planet, would be to set up solar-powered, greenhouse-gas producing factories.
