AnnZ [28]

Answer:

Pressure will double

Explanation:

Gay - Lussac Law => P ∝ T with volume and mass held constant.

=> P₁/T₁ = P₂/T₂ => P₂ = P₁T₂/T₁

T₂ = 2T₁

P₂ = P₁(2T₁)/T₁ = 2P₁

Double absolute temperature => double pressure

PLEASE HELP ME If a radioactive substance has an initial mass of 50 grams

Yuri [45]

Answer: $3.125\ g$

Explanation:

Given

Initial mass $A_o=50\ g$

half-life is $T_{\frac{1}{2}}=5\ years$

At any time the left amount is given by

$A=A_o2^{-\dfrac{t}{T_{\frac{1}{2}}}}\\\\\text{Insert the values}\\\\A=50\cdot 2^{-\dfrac{20}{5}}\\\\A=50\cdot 2^{-4}\\\\A=\dfrac{50}{16}\\\\A=3.125\ g$
