The melting point of californium is: 900 0C.
The mass of the balloon depends on its size. For small sized balloon, weighing scale can be used to calculate the mass. Anything that has mass will have gravitational force acting on it.
It is predicted that Rutherfordium has a melting point of 2100 C.
Freezing point: 273.15 K Melting point: 373 K
The melting point of CuSO4.5H2O is 152 0C.
You simply subtract the melting point of steel, minus the ambient temperature.
The melting point of sodium bromide (a salt) is 755 . Calculate this temperature in and in kelvins.
Chocolate is a mixture and therefore doesn't have a well defined melting point. The temperature at which any given block of chocolate melts depends upon its composition.
It's almost always much, much easier to measure the melting point of something (or just look it up) than it is to attempt to calculate it.
Impossible to calc any melting or boiling points.
Bromine, as many other materials gets a higher melting point when pressure is low [less energy is needed to set molecules free] and lower melting point when pressure is high [more energy needed].
Melting and boiling points are important characteristics of materials: they are needed in industry and in laboratory.
1) they have high melting and boiling point
This is the melting point.

Since each compound has a specific melting point, knowing the melting point can narrow down the possibilities so that only a few additional tests are needed to identify the compound.
