Why do Bees Die when they Sting us?

Honeybees are the only bees that die after stinging.

But if they die, why do they sting?

Bees only sting when they feel we are a threat to their queen or their hive. Now, the stinger of a honeybee is barbed. After stinging, it can easily come out, if the skin is thin. But since human skin is thick, the barbed stinger gets stuck. Hence, when the bee tries to pull herself, she ends up tearing the abdomen, leaving behind her venom sac, parts of the digestive tract, etc., and thus, killing herself. Now, although the bee is dead, we should make sure that we remove the sting. This is because in spite of being detached from the bee, the venom sac continues to pump venom, thus increasing the pain.

How Energy conversion from coal is done?

Single generator sets of over 600 MW are now used in the UK, though there are many smaller generators in use. A 600 MW generator can supplythe average needs of over 1 million UK households. Three or four such generators are typically installed in a single large coal-fired station which isoften sited close to a coal mine, away from the city dwellers who consume the electricity. Such generators are usually driven by a compound arrangement of highpressure, intermediate-pressure and low-pressure turbines, increasing in size as the pressure decreases. Modern turbines rotate in a speed range from 1500 to 3500 r.p.m., usually 3000 r.p.m. for the UK’s 50 Hz system. For large coal-fired plant the steam pressure could be 25 megapascals (MPa) with steam temperatures of 500–600 °C to improve the thermodynamic efficiency. In nuclear reactors, which operate under less demanding conditions, the steam is superheated to about 5 MPa and 300 °C. Modern water tube boilers are complex and have ...
