Line d represents water. if the atmospheric pressure in a flask is lowered to 70 kpa, water would boil at what temperature?
sp2606 [1]
The diagram is in the picture attached.
Options are:
A) 32 °C
B) 70 °C
C) 92 °C
D) 100 °C

In order to find the value required, you need to look at the diagram and follow these steps:
1) search for the value of 70 kPa on the y-axis;
2) move on a horizontal line towards the right until you reach the line D;
3) move on a vertical line down, towards the x-axis;
4) read at what value of °C you are at.

Doing so, you can see that you are at a value a little bit above 90 °C (see picture).

Hence, the correct answer is C) 92°C.

Suppose the initial kinetic energy and final potential energy in an experiment are both zero. What can you conclude? A. The fina
My name is Ann [436]

Answer:

C. The final kinetic energy is equal to the initial potential energy.

Explanation:

Based on the Principle of energy conservation:

Sum of the Initial Energy = Sum of the Final Energy

Initial Kinetic Energy + Initial Potential Energy = Final Kinetic Energy + Final Potential Energy..........(1)

Since according to the question:

Initial Kinetic Energy = 0

Final Potential Energy = 0

The equation (1) above reduces to

Initial Potential Energy = Final Kinetic Energy

Potential energy is the energy an object has because of its __________.
jasenka [17]

Answer:

option D

Explanation:                                    

The correct answer is option D  

Potential energy of an object is because of its location.

 Expression of potential energy      

     P E = m g H                                  

where H is the height of the object.            

           g is acceleration due to gravity, 9.8 m/s²

           m  is the mass of the object.          

Potential energy is directly proportional to the location of the object.    

If the height of the object is more than the potential energy of the object will also increase.
