How does the heat get to the mercury in the bulb? (ie. there are only three ways to transfer heat: convection, radiation or conduction). So what does the heat do to the glass?salemchic05 said:I have a concept question that asks, "When the bulb of a mercury-in-glass thermometer is inserted into boiling water, the mercury column first drops slightly before it begins to rise. Account for this phenomenon." I have no idea why. Any ideas?

Temperature is a measure of the average kinetic energy of the particles in a substance, while heat is the total energy transferred between two objects due to a difference in temperature.
Temperature and heat are directly proportional to each other, meaning that as the temperature increases, so does the amount of heat transferred.
Temperature is typically measured in degrees Celsius (°C) or Kelvin (K), while heat is measured in joules (J).
Thermal equilibrium is achieved when two objects or systems reach the same temperature, and there is no net transfer of heat between them.
Heat can be transferred through three methods: conduction, convection, and radiation. Conduction is the transfer of heat through direct contact, convection is the transfer of heat through the movement of fluids, and radiation is the transfer of heat through electromagnetic waves.
