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.

the answer is: trichonympha lives in the gut of termites and digests cellulose eaten by the termite.

this is an example of a symbiotic association of a protozoan with its mode of association.
