Question

Two spheres are made of same substance have diameter in the ratio 1:2 their thermal capacities are in the ratio of

Answer 1

hey mate

here is your answer

specific heat capacity is the characteristic property of a body.so it doesn't depend upon the mass of the body.however,it depends upon the substance or the material of the body.however,the thermal or heat capacity of the body depends upon the mass of the body.

now, let's get back to your question

question: two spheres....


answer: as mentioned above,the specific heat capacity doesn't depend upon on the mass,but thermal or heat capacity of the body depends upon in it.

since the material is same, so both will have the same density

but as their diameter are different
thus, their radii are also different

the volume of the sphere is directly proportional to the cube of the radius

thus,the ratio of the volume would be 1:8.

and thus their mass would also be in ratio 1:8 as density is constant.

thus ,the ratio of their thermal capacity would also be 1:8 (answer).

Answer 2

the answer is 1/8 bcz of density and specific hear capacity constant so volume we can take and the answer will be 1/8
