What is the final temperature when 625 grams of water at 75.0 C loses 7.96 x 10 to the fourth power J ? The specific heat of wat
IgorLugansk [536]

The final temperature : 44.5 °C

<h3>Further explanation</h3>

Heat can be formulated :

Q = m . c .Δt

Q = heat, J

m = mass, g

c = specific heat, J/gC

Δt= temperature

m= 625 g

Q=7.96 x 10⁴ J

c = 4.18 j/gC

t₁=75 C

\tt Q=m.c.\Delta t\\\\7.96\times 10^4=625\times 4.18\times (75-t_2)\\\\75-t_2=30.5\\\\t_2=44.5^oC

When the pressure on a solid is greatly increased, the volume of the solid shows almost no change.
Veronika [31]

Answer:

The volume of the solid shows no change

Explanation:

Pressure only affects gaseous system. This is because the force of cohesion between the gaseous molecules are negligible(i.e very small) and their molecules are far apart hence the gaseous molecules are easily compressed. But for solid, the Particles are very close and tightly packed together with a strong force of cohesion hence pressure has no effect on it. This account for the definite shape and definite volume of solid
