If the temperature of the helium balloon were increased from 30°C to 35°C and the volume of the balloon only expanded from 0.47L to 1.55L, how much pressure would be inside the balloon?

Explanation:

To solve this problem, we can use the Combined Gas Laws:

Data:

p₁ = p₁; V₁ = 0.47 L; n₁ = n₁;  T₁ = 30 °C

p₂ = ?;  V₂ = 1.55 L; n₂ = n₁; T₂ = 35 °C

Calculations:

(a) Convert the temperatures to kelvins

T₁ = (30 + 273.15)K = 303.15 K

T₂ = (35 + 273.15)K = 308.15 K

(b) Calculate the new pressure

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
