why the human body temperature always remains constant in normal person
Body temperature remains relatively constant regardless of external weather conditions. However, extreme cold or hot weather can affect how the body maintains its temperature through mechanisms like shivering or sweating to keep it within a normal range.
The temperature. A liquid will increase in temperature until it reaches the boiling point temperature. At this temperature the liquid will become a gas. Under normal circumstances, the liquid cannot get any hotter than the boiling point without becoming a gas. So the liquid remains the same temperature until it has all boiled away.
Hyperthermia and hypothermia are what the rapid change in body temperature is called. Someone who is experiencing hyperthermia has a temperature that remains above normal. Someone who is experiencing hypothermia has a temperature that remains below normal.
98.6 Fahrenheit or 37 Celsius is the normal temperature for humans.
At normal pressure, it will be 0 deg C until all the ice has melted.
False
The mass constant of a proton is approximately 1.67 x 10^-27 kg. This value represents the mass of a proton in kilograms and remains constant under normal conditions.
It means that the freezing or melting points do not change, that they are always the same, depending on the type of matter. For eg. the melting point or freezing point of water is 0○ Celsius and the boiling point is always 100○C.
The accepted 'normal' figures are 98.6°F or 37°C - however, there are always exceptions !

False
The base-emitter voltage (V_BE) in a bipolar junction transistor (BJT) is typically around 0.7 volts for silicon transistors when in the active region. This voltage remains relatively constant because it is determined by the built-in potential of the semiconductor junction and the thermal voltage, which is influenced by temperature. As current flows through the junction, the V_BE adjusts slightly to maintain the balance of charge carriers, but it generally stays close to this value under normal operating conditions. Consequently, it is considered constant for practical purposes in circuit analysis.
