Question

A 3-kg object experiences a temperature rise of 50°C when 1000 joules of heat are added. Using the same substance, which situation would require the same amount of heat to be added? A) A 6-kg mass experiences a temperature rise of 50°C. B) A 3-kg mass experiences a temperature rise of 50°C. C) A 6-kg mass experiences a temperature rise of 100°C. D) A 3-kg mass experiences a temperature rise of 100°C.

Answer 1

Answer:

B

Explanation:

This option is exactly the same as the example. Thus it would require the same amount of heat.

Answer 2

Answer:

B) A 3-kg mass experiences a temperature rise of 50°C.

Explanation:

As we know that the rise in temperature for 3 kg object is 50 degree C then the heat added is given as 1000 J

so here we can say that formula of heat is

$Q = ms\Delta T$

here we will have

$m = mass$

s = specific heat capacity

$\Delta T$ = temperature rise

so here if we make all three parameters same to make this heat energy same

so correct answer will be

B) A 3-kg mass experiences a temperature rise of 50°C.
