Why is graphite used as a lubricant

2 answers:

There are weaker covalent bonds between these layers, hence they can easily slide over each other. Due to this, it is a lubricant, since the layers slide over each other so easily. ... Graphite is a mineral made of loosely bonded sheets of carbon atoms, giving it a slippery texture that makes it a very effective lubricant.

1.What is the specific heat capacity of granite when 20 kg absorbs 237 000 J of heat energy, causing its temperature to increase

Natalka [10]

<u>Given</u> :

Amount = 20 kg
Heat energy absorbed = 237,000 J
Temperature change = 15 °C

<u>Formula applied</u> :

$\boxed {Q = mc \triangle T}$

Q = absorbed heat
m = mass
c = specific heat capacity
ΔT = temperature change

Let's solve for c !

⇒ 237,000 = 20 × c × 15

⇒ c = 237,000 ÷ 300

⇒ $\boxed {c = 790 J kg^{-1} K^{-1}}$

∴ The specific heat capacity of granite is <u>790 J kg⁻¹ K⁻¹</u>.
