A 10.0-kg block of gold is heated in the Sun from 25.0℃ to 30.0℃. Use the table (Specific heat table) to help calculate the change in the block's thermal energy.

900 J
1300 J
6400 J
3900 J

Q = 6450 j

Explanation:

Given data:

Mass of gold = 10 kg (10×1000 =10,000 g)

Initial temperature = 25°C

Final temperature = 30°C

Energy absorbed = ?

Solution:

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

Specific heat capacity of gold = 0.129 j/g.°C

ΔT = 30°C - 25°C

ΔT = 5°C

Q = 10,000 g ×0.129 j/g.°C× 5°C

Q = 6450 j

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
