The electron is negatively charged, while the nucleus is positively charged.

Protons and electrons, two of the subatomic particles, each have an electrical charge of one or the other. On the other hand, neutrons lack a charge. Protons and neutrons make up the nucleus (or core) of an atom. Where an atom belongs on the Periodic Table is essentially determined by the number of protons in its nucleus, or "atomic number." The features of an atom are also largely determined by the number of protons in the nucleus.

Hence, electron is negative charge particle and proton is positive charge particle both present in equal proportion to neutral atom.

Say I grab a bunch of aluminum foil (9.5g) and ball it up. Aluminum has a specific heat of .9J/g*C. How much would the aluminum’
Brrunno [24]

Answer:

ΔT = 0.78 °C

Explanation:

Given data:

Mass of Al = 9.5 g

Specific heat capacity of Al = 0.9 J/g.°C

Temperature change = ?

Heat added = 67 J

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

67 J = 9.5 g × 0.9 j/g.°C × ΔT

67 J = 85.5 j/°C × ΔT

ΔT = 67 J  /  85.5 j/°C

ΔT = 0.78 °C
