You can spray alcohol inside a car for disinfection, but the car must be turned off and kept in a non-operational state. At the same time, it is important to ensure proper ventilation in the car. Since 75% alcohol has a flash point around 22 degrees Celsius and evaporates quickly, car owners must strictly avoid any open flames nearby and control the amount of alcohol used to prevent excessive alcohol concentration in the air, which could lead to an explosion. Seventy-five percent alcohol is effective in inactivating viruses because alcohol molecules have strong permeability, allowing them to penetrate the membrane of bacteria, enter their interior, and coagulate the proteins that form the basis of bacterial life, thereby killing the bacteria.

Is a 120°C Water Temperature Normal for a BMW 5 Series?

The BMW 5 Series does not have a water temperature gauge, but it is equipped with an automatic water temperature regulation and warning system. A temperature of 120°C is considered normal. The normal operating temperature for a BMW engine is 120°C. Water Temperature Gauge Range: The water temperature gauge ranges from 0-130°C, with the normal temperature being 90°C at the center. When the water temperature stabilizes at 90°C, it indicates that the engine's heat generation has stabilized, reaching its optimal working condition. Overheating: If the car's water temperature becomes too high, the driver should stop and let the vehicle cool down to the normal temperature before continuing to drive. Reading the Water Temperature Gauge: On the water temperature gauge, 'C' represents 60°C, and the 'H' red mark represents 110°C. The span from 60-110°C allows for an estimation of the approximate temperature indicated by the gauge.
