Explanation:
heat lost by water will be used to increase the temperature of ice
heat gained by ice
= mass x specific heat x rise in temperature
1 x 2090 x t
heat lost by water in cooling to 0° C
= mcΔt where m is mass of water , s is specific heat of water and Δt is fall in temperature .
= 1 x 2 x 4186
8372
heat lost = heat gained
1 x 2090 x t = 8372
t = 4°C
There will be a rise of 4 degree in the temperature of ice.
Answer:
Solenoid is the correct answer
Transpiration is the evaporation of water through leaf stomata. It is the major force moving water through plants. Cohesion and adhesion create tension within xylem that helps move water upward.
Since the speed of sound is very high, we consider the time period of thunder and lightening negligible.
Now, d = vt
thus, d = 343 x 16.2
thus, d = 5556.6 metres
Thus, we are 5556.6 metres away from lightening ( approximately)
