How is energy being transformed from wind to electric energy? Wind turbines use blades to collect the wind’s kinetic energy. Wind flows over the blades creating lift (similar to the effect on airplane wings), which causes the blades to turn. The blades are connected to a drive shaft that turns an electric generator, which produces (generates) electricity.
Can you cook dry pasta in a pressure cooker? When you cook pasta in a pressure cooker, you don’t have to watch it or monitor the heat underneath the pot. It cooks quickly and unattended in a pressure cooker. Also, you can cook pasta directly in a sauce in a pressure cooker, which saves you having to do one more step in a recipe and one more pot to clean up.

Why can graphite conduct electricity but diamond can’t?
Graphite can conduct electricity because of the delocalised (free) electrons in its structure. These arise because each carbon atom is only bonded to 3 other carbon atoms. … However, in diamond, all 4 outer electrons on each carbon atom are used in covalent bonding, so there are no delocalised electrons. 13.
