Borax, also known as sodium borate, sodium tetraborate,
or disodium tetraborate, is an important boron compound,
a mineral, and a salt of boric acid. Powdered borax is white,
consisting of soft colorless crystals that dissolve easily in water.
Its molecular (chemical) formula is <span>

Answer:
Polar covalent bond or just covalent bond
Explanation:
Answer: if the pressure in the container is doubled, then the temperature will double too.
Justification:
You can rely on Gay-Lussac's law for ideal gases to answer the question.
According to that law, the pressure and temperature of a fixed amount of gas in a closed rigid container (constant volume) varie in direct proportion.
Mathematically, you can write in this way:
P/T = k
P₁ / T₁ = P₂ / T₂
That means, that if the pressure in the container is doubled, then the temperature will double too.
You can see that mathematically:
P₂ = 2 P₁
T₂ = (T₁ / P₁)(P₂) = (T₁ / P₁) (2 P₁) = 2 T₁
Answer:
∆PE = 749.7 J
At 0.9 m high, PE = 793.8 J
At 1.75 m high, PE = 1543.5 J
