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

B

Step-by-step explanation:

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

Answer 2

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

Step-by-step 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.
