Question
A furnace takes 10 minutes to heat up to reach 1000 °C.Pure aluminium is placed in the furnace.After 6 minutes will the pure aluminium be solid or a molten liquid?Molten liquid because at 6 minutes the temperature in the furnace is greater than the melting point of aluminium.Molten liquid because at 6 minutes the temperature in the furnace is less than the melting point of aluminium.Solid because at 6 minutes the temperature in the furnace is greater than the melting point of aluminium.Solid because at 6 minutes the temperature in the furnace is less than the melting point of aluminium.I DON'T KNOWSUBMIT ANSWER
Solution
The answer to this question depends on the melting point of aluminium. The melting point of aluminium is 660.32 °C. If the furnace heats up uniformly, then in 6 minutes it would be at 600°C (since it reaches 1000°C in 10 minutes). This is less than the melting point of aluminium. Therefore, the aluminium would still be solid. So, the correct answer is "Solid because at 6 minutes the temperature in the furnace is less than the melting point of aluminium."
