I would say the answer is emissions. These are the particles that are not supposed to be present in air but due to the production of different substances from humans daily activities these substances go with the air we breath. Hope this helped.
Helium at room temperature is Gaseous
hope that helps
Answer:
477 °C
Explanation:
Step 1: Given data
- Initial pressure (P₁): 1.0 atm
- Initial temperature (T₁): 27 °C
- Final pressure (P₂): 2.5 atm
Step 2: Convert 27 °C to Kelvin
We will use the following expression.
K = °C + 273.15 = 27 + 273.15 = 300 K
Step 3: Calculate the final temperature (T₂)
If we assume constant volume (before the can explodes) and ideal behavior, we can calculate the final temperature using Gay-Lussac's law.
T₁/P₁ = T₂/P₂
T₂ = T₁ × P₂/P₁
T₂ = 300 K × 2.5 atm/1.0 atm = 750 K
In Celsius,
°C = K - 273.15 = 750 - 273.15 = 477 °C
<span>In an equation, the symbol that would indicate a mixture is c (aq). The meanings of the symbols are: (s) - solid, (l) - liquid, (g) gas, and (aq) - aqueous. Symbol (aq) means that something is dissolved in the water. It represents an aqueous solution. </span>
Answer:
666.67 kg is the mass of a car.
Explanation:
Momentum is defined as amount of motion possessed by the the moving body. It is mathematically calculated by multiplying mass into velocity by which object is moving.
Mass of the car = m =?
Velocity of the car = v = 15.0 m/s
Momentum of the car = P = 10,000.00 kgm/s
666.67 kg is the mass of a car.
