Explanation:
Density: is the ratio between the mass of an object and its volume.
density = mass/ volume. Its units are g/ml, g/cm³ or kg/m³.
What does it tell you about the substance?
Density tells the degree of compactness of a substance. It could tell if the substance is solid or it is porous.
Answer:
P₂ = 1102 Kpa
Explanation:
Given data:
Initial pressure = 1000.0 Kpa
Initial temperature = 20.0°C
Final temperature = 50.0°C
Final pressure = ?
Solution:
Initial temperature = 20.0°C (20+273 = 293 K)
Final temperature = 50.0°C (50+273 = 323 K)
According to Gay-Lussac Law,
The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.
Mathematical relationship:
P₁/T₁ = P₂/T₂
Now we will put the values in formula:
1000 Kpa / 293 K = P₂/323 K
P₂ = 1000 Kpa × 323 K / 293 K
P₂ = 323000 Kpa. K /293 K
P₂ = 1102 Kpa

Explanation:
Answer: 190.9K
Explanation:
5.6(14) = 5(.0821)T or (5.6*14)/(5(.0821))
78.4 = 0.4105T
190.9K = T
