I copied this off a fan help site, so if it's to confusing please take a look on tip.it

"Use the spade on the Bunsen Burner on the table.
Now use the spade on the door.
After this use the Cupric Sulfate with the door.
Examine a vial of liquid. It should say "Dihydrogen monoxide" when you examine it. Now use this one on the door as well.
The spade will now be stuck in the door so you can pull the door open with it.

Miss Cheveers, door two

For the second door, use Gypsum and another vial of Dihydrogen monoxide with the tin.
Now use the tin with the key chained to the wall.
After this use the Cupric ore powder and Tin ore powder on the tin.
Use the tin on the Bunsen Burner.
Now use either a knife or a bronze wire on the tin to get the key.
Go to the door and use the key on it."

I hope this is the answer you needed.
