Answer:

5850\ \text{cal}

Explanation:

m = Mass of water = 4500 g

c = Specific heat of water = 1\ \text{cal/g}^{\circ}\text{C}

\Delta T = Change in temperature of water = 1.3^{\circ}\text{C}

Heat is given by

q=mc\Delta T\\\Rightarrow q=4500\times 1\times 1.3\\\Rightarrow q=5850\ \text{cal}

A slice of the bread contains 5850\ \text{cal}.
