The melting points then get gradually lower, with the element caesium four places down having a melting point of 28°C. A hypothesis is a suggestion or prediction made on the basis of some evidence.

The hazardous device was ultimately found near the town of Newman, located along a 1400 km (870 mile) route from the Gudai-Darri mine to Perth On 25 January, when mining company Rio Tinto reported ...

The casing contains a small quantity of radioactive Caesium-137, which could cause serious illness if touched. It was lost between the town of Newman and the city of Perth in mid-January - a ...
