- 1 mm/min = 1.66667E-5 m/s
- 1 m/s = 60000 mm/min
<u>Now</u><u>,</u><u> </u><u>come</u><u> </u><u>to</u><u> </u><u>the</u><u> </u><u>question</u><u> </u><u>-</u><u> </u>

Result : 2536 mm/min = 0.0422666667 m/s.
Answer;
A. 2.48 MJ
Explanation;
-Heat energy may be given by the product of specific heat capacity , mass and change in temperature, or the product of heat capacity and change in temperature.
-When a substance is changing from solid state to liquid state then the heat energy is calculate by multiplying the latent heat of fusion of a substance by the mass. Latent heat of fusion of ice =3.34×10⁵J/kg and specific heat capacity of water is 2100 J/kg/K.
Specific heat energy: Q = mcΔT
Latent heat energy: Q = mLf
In this case the heat energy required will be;
Heat required to melt ice and raise its temperature to 0°C:
Q₁ = mLf+mciΔT
Q₁ = (7 kg*3.34×10⁵J/kg) + ((7kg*2100J/kgK*{0°C-(9°C)})
= 2.48 MJ (MEGA JOULES)
Answer:
273.15
Explanation:(32°F − 32) × 5/9 + 273.15 = 273.15K
Answer: The voids between stars in our galaxy can be filled with tenuous clouds of gas and other molecules. ... That material gets "ripped away" from the galaxies by the force of gravity, and often enough it collides with other material.
