Answer:

v?

Explanation:

v = ∆s / ∆t

v =?

∆s = 236 - 218 = 18km

=t = 10: 30 - 10:15 = 15 minutes to hour 15/60 = 0.25h

v = 18 / 0.25

v = 72km / h

speed of 72km / h

How much energy must be removed from a 450 g block of ice to cool it from 0∘c to -20 ∘c?

frutty [35]

<span>The energy removed from a 450 g block of ice can only be done with a few options: a colder freezing facility, liquid nitrogen, or stopping the energy at all and adding dry ice for a brief period. The 450 g block should loose heat energy faster in a thermostat set at -20 degrees just to maintain the ice formation.</span>
