Assuming the teacher means zero Fahrenheit, the same temperature is minus 17.7 degrees Celsius. If the zero is Celsius, changing it to Fahrenheit gives you 32 degrees. But, the teacher said it's going to be twice as cold, and that is something completely different and more complicated.
Beethoven is considered the transitional figure between Classical composers Haydn and Mozart on the one hand, and the Romantics on the other. His innovations included his construction of his Sixth Symphony (The Pastoral) as program music and his expansion of the quartet, concerto, sonata, and symphony forms.
Ludwig van Beethoven is considered one of the greatest composers of all time. His compositions broke barriers, brought about the romantic era in classical music, and were influenced by what was going on around him. The 18th century was called the Baroque period, and Vienna was a Baroque city. In one sense of the word, baroque refers to the type of dramatic architecture that began to spring up throughout the Austro-Hungarian capital.
