Heat capacity of a material is dependent upon the material's mass.
True or false?

Answers

Hello

Answer:

True.This quantity is known as the specific heat capacity (or simply, the specific heat), which is the heat capacity per unit mass of a material. Experiments show that the transferred heat depends on three factors:

(1) The change in temperature,

(2) the mass of the system.

(3) the substance and phase of the substance.


7. Compared with our'Sun, the star Belelgeuse is
smaller, hotter, and less luminous
smaller, cooler, and more luminous
larger, hotter, and less lumulous
larger, cooler, and more luminous

Answers

Answer:

Larger, cooler, and more luminous.

Betelgeuse is red in color, and that means that the surface of it is cooler than the sun (bluish white is hottest, and red is lowest). It is also common knowledge that it is larger, so the correct option would be D. Hope this helped :)

If 5,800 j of energy are applied to a 15.2 kg piece of lead, by how much does the temp change if the specific heat of lead is 0.128

Answers

Answer:

The answer will be 2.98K

Explanation:

Using the formula:

Q = mc∆T

Q= 5,800 (heat in joules)

m= convert 15.2kg to g which is 15200g (mass in grams)

c= 0.128 J/g °c (Specific heat capacity)

∆T=  what we need to find (temperature change)

5800J = 15200g x 0.128 x ∆T

= 2.98K
