User: Which of the following accurately describes the behavior of water when subjected to temperature change?
Question 2 options:
A)
A mass of water will contract if cooled from 1°C to 0°C.
B)
The volume of water will increase if cooled from 3°C to 2°C.
C)
The volume of water will decrease if heated from 6°C to 7°C.
D)
A mass of water will expand if heated from 0°C to 2°C.
Weegy: The volume of water will increase if cooled from 3 C to 2 C accurately describes the behavior of water when subjected to temperature change.
User: A 3.8 kg object is lifted 12 meters. Approximately how much work is performed during the lifting?
Question 3 options:
A)
372.4 J
B)
588 J
C)
446.9 J
D)
45.6 J
Weegy: A 3.8 kg object is lifted 12 meters. 446.9 J of work is performed during the lifting.
Solution:
W = mgh;
W = (3.8 Kg)(9.8 m/s )(12 m);
W = 446.88 J or 446.9 J.
User: Suppose that a block is pulled 16 meters across a floor. What amount of work is done if the force used to drag the block is 22 N?
Question 4 options:
A)
330 J
B)
220 J
C)
352 J
D)
200 J
Weegy: Suppose that a block is pulled 16 meters across a floor. 352 Joules of work is done if the force used to drag the block is 22 N.
Solution:
Work done = Force * Displacement = 22N * 16m = 352 Nm; Work done = 352 Joules.
User: A 6.7 kg object moves with a velocity of 8 m/s. What's its kinetic energy?
Question 5 options:
A)
214.4 J
B)
26.8 J
C)
167.5 J
D)
53.6 J
Weegy: A 6.7 kg object moves with a velocity of 8 m/s. Its kinetic energy is 214.4J.
Solution:
kinetic energy = 1/2 *m*v? Kinetic energy =1/2 * 6.7* 8 *8 = 214.4J.
User: Which one of the following temperatures is equal to 5°C?
Question 6 options:
A)

B)
278 K
C)
41 K
D)
465 K
Weegy: 278 K is equal to 5 C.
