The enthalpy of an intermediate step should be manipulated when used to produce an overall equation by using the Hess's law. You could multiply the enthalpy by -1 if this equation is reversed in theory.

An 80.0g sample of an unknown metal is at an initial temperature of 55.5oC. Afer 540 J of energy is absorbed by the metal, the t
Lunna [17]

Answer:

Specific heat of metal = 0.26 j/g.°C

Explanation:

Given data:

Mass of sample = 80.0 g

Initial temperature = 55.5 °C

Final temperature = 81.75 °C

Amount of heat absorbed = 540 j

Specific heat of metal = ?

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 =  81.75 °C - 55.5 °C

ΔT =  26.25 °C

540 j = 80 g × c × 26.25 °C

540 j = 2100 g.°C× c

540 j / 2100 g.°C = c

c = 0.26 j/g.°C

Why do you think water boils when the vapor pressure is equal to atmospheric pressure?
lesya692 [45]

Answer: why do I think that water boils when the vapor pressure is equal to the atmospheric pressure?

because The pressure level of a liquid lowers the number of pressure exerted on the liquid by the atmosphere. ... pressure level may be increased by heating a liquid and causing more molecules to enter the atmosphere. At the purpose where the pressure level is up to the air pressure boiling will begin.

Explanation: I hope this helps, have a good day :)
