d. A calorimeter has mass 100 g and specific heat \( 0.1 \mathrm{kcal} / \mathrm{kg}{ }^{\circ} \mathrm{C} \). It contains 250 gm of liquid at \( 30{ }^{\circ} \mathrm{C} \) having specific heat of \( 0.4 \mathrm{kcal} / \mathrm{kg} \) \( { }^{\circ} \mathrm{C} \). If we drop a piece of ice of mass 10 g at 0 . C , What will be the temperature of the mixture?

There are different types of food coloring available in most grocery stores- one that is water-based, and one that is oil-based. The oil-based food coloring works best in chocolates, in fry-oil to color fried foods, and in food with high butter contents. Based off of this information and knowing that substances of like polarity mix readily with one another, which food coloring is more polar (water-based or oil-based)? Which food coloring is less polar (or even nonpolar)? Water-based [Choose ]
