Answer:
Q = 114895 J
Explanation:
To find the thermal energy gained by the ice you use the following formula:
m: mass of the ice = 0.250kg
T2: final temperature = 22°C
T1: initial temperature = -8.0°C
Hf: heat of fusion of water = 3.34*10^5 J/kg
c: specific heat of water = 4186 J/kg
By replacing the values of the parameters you have:
where you have considered that ice melts completely
Answer:
Explanation:
Given:
- Length of block,
- Breadth of block,
- height of block,
- Thermal conductivity of the block,
- Temperature on the hotter side,
- temperature on the cooler side,
- time for which the heat flows,

<em>The rate of heat flow using </em><em>Fourier's law</em><em> of conduction is given as:</em>
<u>Now the amount heat flow perpendicular to the pink surface:</u>
<u>Now the amount heat flow perpendicular to the orange surface:</u>
<u>Now the amount heat flow perpendicular to the green surface:</u>
