What is an intensive property

In chemistry, an intensive property is a property that depends on the type of matter in a sample.

On a trip to Italy Cheyne rented a car to tour the country As he turned onto the highway he noticed that the speed limit was 95 kmh How fast can Cheyne drive in mph

Cheyne can drive 59 mph.

Which process would be most appropriate to separate a mixture

Filtration. :)

Is odor an extensive or intensive property

intensive

Molten iron is extremely hot averaging about 1500C The specific heat of iron is 0.46 JgC How much heat is released to the atmosphere when 1kg molten iron cools to room temperature 25C

0.46 * 1475 = 678.5 Kjoules (The specific heat is given in terms of joules/ gramme/degC, whilst the question refers to 1kg ie 1000g )
