Answer:
The new volume of the balloon be 
.
Explanation:
We have,
Initial volume is 556 cm ³
The temperature of the balloon decreases from 278 K to 231 K.
We need to find the new volume of the balloon if the pressure is constant.
The Charles law states that at constant pressure, the volume of gas is directly proportional to its temperature i.e.
, P is constant
So, the new volume of the balloon be .
Answer:
The sample will look expanded and occupy more space.
Explanation:
Since, the pressure is constant here, but the temperature is changed. Therefore, according to Charles' Law Volume is directly proportional to Temperature, provided the pressure is kept constant. Mathematically:
V1/T1 = V2/T2
V1 = (T1/T2)(V2)
V1 = (300 k/450 k)(V2)
<u>V1 = (0.67)V2</u>
The equation indicates that The fina volume of the gas V2 will be greater than the initial volume V1. <u>Thus, sample will look expanded and occupy more space than the previous state.</u>
