Mean value of temperatures = \(\frac{t_1 + t_2}{2}\) °C.
Boiling point of water = ______ °C.
The melting point of ice = ______ °C.
Answer (1)
The question involves understanding basic properties related to temperature, which is a concept generally discussed in Physics.
When discussing temperatures in the context of water:
Boiling Point of Water:
The boiling point of water is 100°C at standard atmospheric pressure (which is 1 atmosphere or 101.3 kPa). This is the temperature at which water transitions from a liquid to a gas. It's a common reference point in science due to water's essential role in heat and temperature studies.
Melting Point of Ice:
The melting point of ice is 0°C at standard atmospheric pressure. This is the temperature at which ice, the solid form of water, transitions to its liquid form.
These points are essential in understanding phase changes and are used as standard benchmarks in temperature measurements in both scientific and educational contexts.
Mean Temperature Formula:
The formula given, 2 t 1 + t 2 , represents the mean or average temperature. This formula is used to find the average of two temperatures, t 1 and t 2 , where you add the two temperatures together and then divide by 2.
Understanding these fundamental concepts is important for exploring more advanced topics in chemistry and physics, such as studying the behavior of substances under various temperatures and pressures.
