Full Question:
What is the temperature of a system in thermal equilibrium with another system made up of water and steam at one atmosphere of pressure?
A) 0°F
B) 273 K
C) 0 K
D) 100°C
E) 273°C
Answer:
The correction Option is D) 100°C
Explanation:
The temperature above is referred to as the critical point.
it is the highest temperature and pressure at which water (which has three phases - liquid, solid, and gas) can exist in vapor/liquid equilibrium. If the temperature goes higher than 100 degrees celsius, it cannot remain is liquid form regardless of what the pressure is at that point.
There is also a condition under which water can exist in its three forms: that is
- Ice (solid)
- Liquid (fluid)
- Gas (vapor)
That state is called <em>triple point. </em>The conditions necessary for that to occur are:
- 273.1600 K (0.0100 °C; 32.0180 °F) as temperature and
- 611.657 pascals (6.11657 mbar; 0.00603659 atm) as pressure

Answer:
W = 5586[J]
Explanation:
Work in physics is defined as the product of force by a distance.
where:
W = work [J]
F = force = m*g [N]
m = mass = 300 [kg]
g = gravity acceleration = 9.81 [m/s²]
d = distance = 1.9 [m]
Now replacing:
![W=m*g*d\\W=300*9.81*1.9\\W=5586[J]](https://tex.z-dn.net/?f=W%3Dm%2Ag%2Ad%5C%5CW%3D300%2A9.81%2A1.9%5C%5CW%3D5586%5BJ%5D)
Use the Second Law of Newton, which states that Net Force = mass times acceleration
F = m * a
F = 50 kg * 1.5 m/s^2 = 75 N

Answer:
3. 1.8A
Explanation:
Given the following data;
Quantity of charge, Q = 650C
Time = 6 minutes to seconds = 6 * 60 = 360 seconds.
To find the current l;
Quantity of charge = current * time
Substituting into the equation, we have;
650 = current * 360
Current = 650/360
Current = 1.8 Amperes
