Need answer ASAP!! The specific heat capacity of metal A is twice that of metal B. Based on
this information, which of the following statements is true?

The melting point of metal A is higher than that of metal B

The heat of fusion of metal A is twice that of metal B

If the same amount of heat is absorbed by equal masses of metal A and metal B,
the temperature change of metal A will be twice that of metal B

If the same amount of heat is absorbed by equal masses of metal A and metal B,
the temperature change of metal A will be half that of metal B

Sagot :

Answer:

last choice

Explanation:

Specific heat of a metal is    j/kg-c

It says nothing about melting point or heat of fusion

A = twice B   =  2 * j/kg-c       B = j/kg-c

 if   j is constant and mass is the same we can write this more like

    A = 2 /C       and    B = 1/C

  or    A ~  C/2      and   B~  C

now you can see that the temp change in A   will be 1/2   that of B
