Two solid blocks, Block X and Block Y, of equal mass are placed on identical electric heaters. Both heaters are switched on for three minutes, transferring the same amount of thermal energy to each block.
The temperature of Block X increases by 15 ∘C15\text{ }^\circ\text{C}15 ∘C while the temperature of Block Y increases by 30 ∘C30\text{ }^\circ\text{C}30 ∘C.
Which statement explains this difference?
Block X has a higher melting point than Block Y.
Block X has a lower melting point than Block Y.
Block X has a larger thermal capacity than Block Y.
Block X has a smaller thermal capacity than Block Y.
