In appliances such as water heaters and ovens, the heating coils pass heat by radiating the heat into a specific area. A thermostat is set to a desired temperature, and the heater coil produces heat until the desired temperature is reached.
The blood sugar level, blood sugar concentration, or blood glucose level is the amount of glucose present in the blood of humans and other animals. Glucose is a simple sugar and approximately 4 grams of glucose are present in the blood of humans at all times. The body tightly regulates blood glucose levels as a part of metabolic homeostasis. Glucose is stored in skeletal muscle and liver cells in the form of glycogen; in fasted individuals, blood glucose is maintained at a constant level at the
In above glucose sample, the no. of glucose molecules = 0.01 x 6.022 x 10 23 = 6.022 x 10 21. Remember that one mole of any substance contains Avogadro number of particles (may be atoms or molecules or ions etc.). If the substance is molecular, the number molecules will be equal to 6.022 x 10 23.
