Why might the stomata of a leaf close on a hot day?

Despite the fact that the stomata open in response to light, they may close on a hot day in order to conserve water. This is because the heat may cause the water to evaporate out through the stomata, causing the plant to lose water, reducing the water potential inside the leaf.
