Specific Heat Capacities!!?

Question

The specific heat capacities of two copper spheres are in the ration of 1:8. What is the ratio of their radii. ( Please also show working out) - whats the difference between mass and volume?

Answer 1

specific heat capacity is a property of matter ,it does not depend on mass whereas heat capacity of a body depends on mass of the body and specific heat capacity of material of body.

for a solid body ,volume is mass/density

Answer 2

If the radius of the shpere is doubled, then the volume of the sphere will
be increased by a factor of eight. Thus a doubleing of the radius is required
to increase the mass and the specific heat by a factor of eight.

volume of sphere one = 4/3 pi r1 cubed
volume of sphere two = 4/3 pi (r1x 2) cubed

The mass of an object is only proportional to its volume, thus the mass is
not equivalent to volume but only the product of volume times density.

Answer 3

C=c m = c (p V)
where
c- specific heat capacity (J/(K kg))
C is the heat capacity of a body made of the material in question (J/K)
m is the mass of the body (kg)
V is the volume of the body (m^3)
ρ = m/V is the density of the material (kg•/m^3)

V=(4/3)piR^3
R1:R2 = 1:8 so
R2=8R1

C1=c p (4/3)piR1^3
C2= c p (8)^3 (4/3)piR1^3

V2-V1=(4/3)piR1^3((8)^3 -1)
V2-V1=(4/3)piR1^3(511)

The mass and volume of one sphere over the other is over 500 larger.

Answer 4

THat answer is Cp = .239 J / g ok this suggests which you opt for 4.1855 J of skill to upward thrust one million °C of 1 gram of water . different one is Cp = 4.1855 kJ / kg : which potential you opt for 4.1855 KJ to upward thrust one million °C of 1 Kilogram of water. This answer is good because of the fact i'm a chemistry instructor.
