Answer:

When an ice cube sits out on a warm day and melts the heat goes into the ice

Explanation:

When an ice cube sits out on a warm day and melts where does the heat go?

Firstly, temperature is the degree  of hotness or coldness of a body, while heat is the transfer of internal energy due to temperature difference.

When ice melts there is no temperature change. The heat needed to change it from its solid state to its liquid state any noticeable change in temperature is called Heat of fusion Q measured in joules.

Q=mL_{f}

So the heat goes directly to the ice to change its state from solid to liquid without any change in temperature. Only to break its intermolecular force of attraction.

car was moving in a straight road of length 320 km it covered 240 km with an average velocity 75 km/hr then it ran out of fuel a
Stella [2.4K]

The average velocity of the car for the whole journey is 69.57 km/h.

The given parameters:

  • <em>Length of the road, L = 320 km</em>
  • <em>Distance covered = 240 km at 75 km/h</em>
  • <em>time spent refueling, t₂ = 0.6 hr</em>
  • <em>Final velocity, = 100 km/hr</em>

The time spent by the before refueling is calculated as follows;

t = \frac{d}{v} \\\\t_1 = \frac{240}{75} \\\\t_1 = 3.2 \ hours

The time spent by the car for the remaining journey;

t_3 = \frac{320 - 240}{100} \\\\t_3 = 0.8 \ hr

The total time of the journey is calculated as follows;

t = t_1 + t_2 + t_3\\\\t = 3.2 \ hr \ + \ 0.6 \ hr \ + \ 0.8 \ hr\\\\t = 4.6 \ hours

The average velocity of the car for the whole journey is calculated as follows;

v = \frac{total \ distance }{total \ time} \\\\v = \frac{320}{4.6} \\\\v = 69.57 \ km/h
