The subatomic particle that gives off visible light is electrons
Answer:
Four
The 0 following the 5 is not significant, because it is assumed that there is no measurements in the decimal place.
Answer:
The initial pressure was 25.2 Pa.
Explanation:
According to the Gay-Lussac's Law, the pressure of given amount of gas is directly proportional to the temperature in kelvin while volume is kept constant.
Formula:
P₁/T₁ =P₂/T₂
P₁ = Initial pressure
T₁ = Initial temperature
P₂ = Final pressure
T₂ = Final temperature
Given data:
T₁ = 87 K
T₂ = 62.25 K
P₂ = 18 Pa
P₁ = ?
Now we will put the values in formula,
P₁/T₁ = P₂/T₂
P₁ = P₂/T₂×T₁
P₁ = (18 Pa / 62.25 K) × 87 K
P₁ = 0.2892 Pa/k × 87 K
P₁ = 25.2 Pa
The initial pressure was 25.2 Pa.
Answer:
10.67 moles is the answers.hope it helped
Answer:
5528 balloons
Explanation:
Explanation:
At constant pressure and number of moles, using Boyle's law
Given ,
V₁ = 155.0 L
V₂ = ?
P₁ = 1835 psi
P₂ = 1 atm = 14.7 psia
Using above equation as:
Volume of each balloon = 3.5 L
Thus, number of balloons,
