The answer is “D) Volume”
Answer:
The new volume is 66.3 mL
Explanation:
Boyle's law states that pressure and volume are inversely proportional, and that P1V1=P2V2
P1 = 0.428 atm
P2=1.55 atm
V1 = 240 mL
V2 = ??
(0.428)(240)=(1.55)(V2)
102.72 = 1.55x
x = 102.72/1.55 = 66.27 mL.
Answer:
2m/s²
Explanation:
When an object starts or at its state of rest it has an Initial speed U = 0
Final speed = 6m/s
total time taken for the acceleration = 3s
Acceleration =?
Acceleration is the change in velocity (speed) with time
OR
Time rate of change of velocity
Acceleration = <u>Change in Speed(velocity)</u>
Time taken
Hence,
Acceleration = <u> </u><u> </u><u>V - </u><u>U</u><u> </u><u> </u>
t
a = <u>6</u><u> </u><u>-</u><u> </u><u>0</u>
3
a = <u>6</u><u> </u><u> </u>
3
a = 2m/s²
If it was warn - hot water, i would say yes
the warm - hot water would dissolve because of the temperature
