a helium balloon at 28 C has a volume of 1.8 L and a pressure of 102 kPa. what is the volume of the balloon when is rises into the atmosphere where the pressure is 85 kPa and the temperature is 4 C?

V₂ =1.99 L

Explanation:

Given data:

Initial volume = 1.8 L

Initial temperature = 28°C (28+273.15 K= 301.15 k)

Initial pressure = 102 KPa

Final volume = ?

Final pressure = 85 KPa

Final temperature = 4°C (4+ 273.15 K = 277.15 K)

Solution:

Formula:  

P₁V₁/T₁ = P₂V₂/T₂  

P₁ = Initial pressure

V₁ = Initial volume

T₁ = Initial temperature

P₂ = Final pressure

V₂ = Final volume

T₂ = Final temperature

V₂ = 102 KPa × 1.8 L × 277.15 K / 301.15 K × 85 KPa

V₂ = 50884.74 KPa .L. K / 25597.75 K.KPa

V₂ =1.99 L

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
