The balloon's volume is 128 ml when the gas temperature rises to 320.0 K. Explanation: Given the following: T1 (initial temperature) = 300K, V1 (initial volume) = 120ml, T2 (final temperature) = 320 K, V2 (final volume) =?. Pressure is kept constant during this process. From the equation: Given that the pressure stays constant, we have: V2 = Putting the values into this formula yields: V2 = 128 ml, which indicates the volume of the gas when the temperature increases from 300 K to 320 K.
The density of the cube is calculated as follows: 38.234 kg/m³ or 0.038234 g/mL. Explanation: We begin with the formula for volume, which is expressed as m³ where 'm' indicates the side of the cube. Given that the cube’s side is 0.65 m and its mass measures 10,500 grams, this converts to 10.5 kg (as 1000 grams = 1 kg). The volume is calculated as (0.65)³, equaling 0.274625 m³. Density is determined by dividing mass by volume, leading to a density of 10.5 kg divided by 0.274625, resulting in 38.234 kg/m³. To convert, 1 kg/m³ equals 0.001 g/mL, thus resulting in 0.038234 g/mL.
