Gold has a specific heat of 0.33cal/gC. If a 4g gold ring changes from 25C to 37C when placed on your hand, how much heat has it absorbed?

12 cal

48 cal

1.32 cal

15.8 cal

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.  

the dependant variable is spilled water

the independent is the heat
