What is the normal emf of a Weston cell at 20 degree Celsius and how does the emf change when the cell is used at 0 degree?
The normal electromotive force (emf) of a Weston cell at 20 degrees Celsius is approximately 1.018 volts. When the temperature drops to 0 degrees Celsius, the emf of the cell typically decreases slightly due to the reduced activity of the electrolyte and changes in the chemical reaction dynamics. This decrease is usually around 0.001 to 0.002 volts per degree Celsius. Thus, at 0 degrees Celsius, the emf would be lower than at 20 degrees Celsius.

Normal phase of aluminum?
The normal phase of aluminum at room temperature is a solid. You can, however, heat to really high temperatures until it becomes a liquid or even a gas.
What is the main difference between normal JK flip flop and master slave JK flip flop?
A normal JK flip-flop has the output change state based on the input on the leading edge of clock, while the master-slave variety predetermines the output on the leading edge of clock and then effects the actual change of the trailing edge of clock, making it impervious to race conditions.
Is it normal for a transformer to buzz?
Sometimes. It depends on the size of the light (watts), the operating voltage, and the line voltage. Very large high voltage lights often buzz.
What is the temperature before you call it steam?
Steam has a minimum temperature of 212 degrees Fahrenheit or 100 degrees Celsius, because those are the temperature at which water boils under normal pressure. Once steam goes below those temperatures it turns back into water. Steam can be heated above those temperatures under certain conditions and is then called superheated steam.
How density and MACH number change across normal shock wave?
Across a normal shock wave, the density of the flow increases as the shock compresses the gas. The Mach number decreases; it transitions from supersonic (greater than 1) upstream to subsonic (less than 1) downstream of the shock. This change occurs because the shock wave converts kinetic energy into thermal energy, resulting in a rise in pressure and temperature. Consequently, the flow properties adjust to accommodate the conservation of mass, momentum, and energy across the shock.
Is 37.8 degree Celsius normal for your baby?
yes.
What is the normal body temperature of donkey?
it is about 39.5 degree Celsius
Is chlorine gas liquefies at 35 degree celsius under normal pressure a chemical or a physical change?
The liquefaction of chlorine gas at 35 degrees Celsius under normal pressure is a physical change. It involves a change in the state of the substance (from gas to liquid) without altering its chemical composition.
Is 37.2 degree Celsius normal?
37 C is normal human body temperature.
What is normal body temperature in degree Fahrenheit and degrees Celsius?
Normal body temperature in degrees fahrenheit is 98.6 and 37 in degrees Celsius.
Is chlorine gas liquefies at - 35 degree celsius under normal pressure a chemical or a physical change?
The liquefaction of chlorine gas at -35 degrees Celsius under normal pressure is a physical change. This is because the change in state from a gas to a liquid does not alter the chemical composition of the substance, only its physical state.
Whether 36.5 degree Celsius is normal?
For human body temperature, 37 degrees Celsius is normal.
What is the normal body temperature of a buffalo?
37.2 - 38.2 degree Celsius is the normal body temperature of a buffalo.
100 degree Celsius?
the boiling point of water under normal atmospheric conditions.
What is the normal operating temperature for Mercedes e420?
100 Celsius which = 212 Degree Fahrenheit
Are celsius scale degree larger than Fahrenheit degree?
A "degree" on the Celsius scale is larger than a "degree" on the Fahrenheit scale. There are 100 equal intervals (degrees) between 0 °C and 100 °C, the freezing and boiling points of water. There are 180 equal intervals between those same temperatures on the Fahrenheit scale (32 °F and 212 °F). That makes each Celsius degree 1.8 times as large (wide) an interval as the Fahrenheit degree. This is the basis for the "9/5" an "5/9" fractions in the conversion formulas (9/5 = 1.8). Some conversion formulas omit the fractions in favor of multiplying or dividing by 1.8, which is a single step. (see related questions)
Which material has a normal melting point of 146 degree Celsius?
Lead has a normal melting point of 327 degrees Celsius, while zinc has a normal melting point of 419 degrees Celsius. Both of these materials have higher melting points than 146 degrees Celsius.
