Explanation:
B because if more soot comes then the darker they will get.
Answer:
1. 0.98 atm
Explanation:
The following data were obtained from the question:
Mass of unknown liquid (m) = 0.3175 g
Temperature (T) = 99 °C
Pressure (P) = 748.2 mmHg
Volume (V) = 145.0 mL
Gas constant (R) = 0.08206 atm.L/Kmol
1. Determination of the pressure in atm.
760 mmHg = 1 atm
Therefore,
748.2 mmHg = 748.2/760 = 0.98 atm
Therefore, the pressure in atm is 0.98 atm.
Answer:
1. A solid has a definite volume and a shape.
2. Liquids take on the shape of their container and will fill the lowest portion of the container, taking on the shape but not the volume.
3. It may take extreme temperature, pressure or energy but all the matter can be changed.
4. Through sublimation, a substance changes from a solid to a gas without even passing through the liquid phase.
