Q1
Equal masses ($m$) of water and cooking oil start at $25^\circ\text{C}$ in identical cups. Each receives the same thermal energy $Q$ from a hot plate. Specific heat determines the temperature change for a given $Q$; thermal conductivity mainly affects how quickly the liquid becomes uniform in temperature. Which liquid’s temperature increases less?
