Astyrofoam ice box has a total area of 0.950 m2and walls with an average thickness of 2.50 cm. the box contains ice, water, and canned beverages at 0ºc . the inside of the box is kept cold by melting ice. how much ice melts in one day if the ice box is kept in the trunk of a car at35.0ºc ?

The mass of the ice is 3.44 kg.

Explanation:

Given that,

Area of ice box A= 0.950 m²

Thickness d= 2.50 cm

Temperature T₁= 0° C

Temperature T₂= 35.0°C

Time t = 1 day = 86400 s

We need to calculate the mass of ice

Using equation of rat of heat transfer by conduction

The heat is used to melt the ice

....(I)

We need to calculate the heat

Put the value of Q in the equation (I)

Hence, The mass of the ice is 3.44 kg.

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
