Equal masses (mm) of water and cooking oil start at 25∘C25^\circ\text{C} in identical cups. Each receives the same thermal energy QQ from a hot plate. Specific heat determines the temperature change for a given QQ; thermal conductivity mainly affects how quickly the liquid becomes uniform in temperature. Which liquid's temperature increases less?
