Answer:
Explanation:
You need the conversion factor to convert the value of 12.33 kPa to milimiters of mercury, mmHg.
The converstion factors are looked at tables, which today you can find in internet.
Since the conversions between kPa and atm and between atm and mmHg are more widely known, I will show the conversion using those relations:
⇒ 101.325 kPa = 760 mmHg
Then, dividing both sides by 101.325 kPa you get the conversion factor:
- 1 = 760 mmHg / 101.325 kPa
Now, multiply 12.33 kPa by that conversion factor:
- 12.33 kPa × 760 mmHg / 101.325 kPa = 92.48 mmHg ← answer
That force is electric force of attraction.
Answer: A closed system, because energy can enter or leave the container, but the water molecules cannot
Explanation:
Open system: In this system energy and matter both have access to their surroundings beyond the boundaries of system. .
Closed system :In this type system only energy has an access to its surroundings beyond the boundaries of system but not matter.
Isolated system:In this type system exchange of both energy and matter are restricted to move outside the boundaries of system.
According to question, the system given is a closed system because energy is transferred from the burner to glass flask and from the glass flask to the water (matter). But water molecules are only getting condensed on the inside surface of the flask that is exchange of matter beyond the boundaries of the system is restricted. Hence, closed system ,A closed system, because energy can enter or leave the container, but the water molecules cannot.
