Answer:
18 kg/cm³
Explanation:Density=mass/ volume=450/25=18kg/cm³
As the volume of gas decreases, the pressure concentration of particles will increase.
Answer:I think it’s self monitoring sorry if wrong
Explanation:
The question above is simply a conversion problem. We are asked to convert from Celsius to Fahrenheit and to Kelvin. To convert from Celsius to Fahrenheit, we do as follows:
°F = (°C<span> × </span>9/5) + 32
°F = (30 × 9/5) + 32
°F = 86
From Celsius to Kelvin,
K = °C + 273.15
K = 30 + 273.15 = 303.15
