Heat energy transferral - the heat energy of the soup is conducted through the liquid and the solid bowl to your hands, as porcelain/plastic bowls are not highly insulated.
Conduction
Room temperature air. The water keeps it fresher.
Its ok as long as you let the water cool to room temperature before adding the water back to the bowl, or adding the betta to the water. Also, it is completely unnesseary to boil before putting in your betta's bowl.
Assuming no loss of heat to the bowl or the air, the temperature of a mixture of two amounts of a substance will be the weighted average of the temperatures of the components - weighted according to their quantities. So the resulting temperature of the above mixture wil be between 55 and 60 degrees C.
Simply it's because Heat and Temperature are not interchangeable. They're not the same thing. Heat is a form of energy. Temperature is not. When heat encounters a substance, it can change the state of the substance or raise it's temperature. Temperature is only a measurement that relates to the molecules kinetic energy. But it says nothing about potential energy. Consider for a moment how much TOTAL potential heat energy is in even a bowl of warm water. You would need a lot of energy to raise a cold bowl of water to that same warm temperature? Could the candle do it? Possibly, but over a long period. That flame might be hot, but it doesn't possess the same energy? Btw: Water has a considerably high Specific Heat, which is the amount of heat (energy) required to raise it's temperature by 1 degree for 1 gram
Convection currents are currents of fluid that move because of a difference in temperature, and therefore energy. When a fluid (let's say water, because we're talking about a bowl of pasta here) heats up closer to the source of heat, it will increase in temperature and energy. Cooler water, which is lower temperature and energy level than warmer water, will gradually sink, which causes the warmer water to rise. When the warm water cools and the cool water warms, the molecules sink and rise respectively. This process continues until the source of heat is extinguished. This is what makes your pasta bowl water move about. Have fun cooking!

yes, by conductivity, as long as the bowl is warmer than your palm
Conduction.
Heat generally tends to flow from higher temperature to lower temperatures. In this case, the cup of milk is hotter than the bowl of tab water. Hence the temperature of water increases, and the temperature of milk decreases. This process continues till both the temperatures are equal.
