Adiver exhales a bubble with a volume of 250 ml at a pressure of 2.4 atm and a temperature of 15 °c. what is the volume of the bubble when it reaches the surface where the pressure is 1.0 atm and the temperature is 27 °c? a. 630mlb. 110 mlc. 580 mld. 1100 mle. 100 ml

Explanation:

We can use the Combined Gas Laws to solve this problem

Data

p₁ = 2.4 atm;  p₂ = 1.0 atm

V₁ = 250 mL; V₂ = ?

T₁ = 15°C;       T₂ = 27 °C

Calculations

(a) Convert the temperatures to kelvins

T₁ = (15 + 273.15) K = 288.15 K

T₂ = (27 + 273.15) K = 300.15 K

(b) Calculate the new volume

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
