A2-kg sample of a metal increases in temperature by 20°c when heated on a stove for 3 minutes. can you predict what will happens to the temperature rise of a 4-kg sample of the same material when heat on the same stove for 6 minutes. a) the temperature change will be approximately 5°c. b) the temperature change will be approximately 80°c eliminate c) the temperature change will be approximately 20°c. d) the temperature change will be approximately 40°c.

C) The temperature change will be approximately 20°C.

Explanation:

Q= heat gained

m= mass of the substance = 2 kg

c = heat capacity = c J/g ° C      

Q=40c Joules

That is in 3 minutes,  heat absorbed = 40 c joules

in 6 minutes, heat absorbed=

Now as the substance is same, the heat capacity will be same.

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
