Elina [12.6K]

Answer:

1.23 j/g. °C

Explanation:

Given data:

Mass of metal = 35.0 g

Initial temperature = 21 °C

Final temperature = 52°C

Amount of heat absorbed = 320 cal  (320 ×4.184 = 1338.88 j)

Specific heat capacity 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 = 52°C -  21 °C

ΔT = 31°C

1338.88 j= 35 g ×c× 31°C

1338.88 j= 1085 g.°C ×c

1338.88 j/1085 g.°C = c

1.23 j/g. °C = c

How does temperature, pressure and surface area affect the dissolving process
larisa [96]
If I am correct, yes. As I was told in chemistry, the surface area affects the dissolving of the "sugar". If you put regular Surat in a hot cup of coffee, it will dissolve at a quick pace, but what if you put the same amount of sugar in the same amour of coffee, but the sugar was fine powder? It would dissolve even faster since it has more surface area. So temperature does affect the dissolving. Hope this helps!
