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
Which process would be most appropriate to separate a mixture
Is odor an extensive or intensive property
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
)
