Yes, it can snow in negative temperatures. Snow can form and fall when the air temperature is below freezing, which is typically below 0 degrees Celsius or 32 degrees Fahrenheit.
The spontaneity of a reaction is determined by the sign of the Gibbs free energy (ΔG). If both enthalpy (H) and entropy (S) are positive, the reaction can be spontaneous at high temperatures where the TΔS term outweighs the positive ΔH term, resulting in a negative ΔG. This means the reaction will be spontaneous at elevated temperatures.
The Kelvin scale is the only temperature scale that does not have negative temperatures. It starts at absolute zero, the lowest possible temperature at which particles have minimal energy and motion.
Lightning does not strike backwards, from the ground to the sky. It only moves in one direction, from the sky to the ground.By striking backwards, do you mean can the Earth give off a lightning bolt to the clouds? No.
Fronts do not occur in the tropics because there is a lack of significant temperature differences in that region. Fronts usually form at the boundaries where air masses with different temperatures meet and mix. In the tropics, the generally uniform warm temperatures do not promote the formation of these temperature contrasts necessary for fronts to develop.
There is no positive and negative on a transformer. Transformers will only pass AC (alternating current), due to the fact that induction will only occur with a moving field. The current has to be changing polarity and intensity continuosly, for the current to be induced in the windings. Both terminals on the output vary, with relation to each other. Put DC into a transformer and the coils will saturate, overheat and probably burn out.
No, a polar molecule is one that has an uneven distribution of electrons, resulting in regions of partial positive and negative charge. This can occur at any temperature, not just low temperatures.
No, a negative multiplied by a negative is a positive, as is of course a positive multiplied by a positive. Only when a negative is multiplied by a positive is the answer negative.
If, and only if the positive value is > the negative value.
No, an O Positive person cannot donate to an A Negative person because the person who is Negative, or Rh Negative, will react to the Positive (Rh Positive) blood. Negative can only get Negative, Positive can get Positive or Negative.
no negative, no positive - only 0
Yes, as long as the mother's blood group is Rh positive, the baby can be Rh positive. Only one parent need be Rh positive for this to occur.
A positive number times another positive number will give you a positive answer. If you multiply two negative numbers together, you will also have a positive answer. The only way to get a negative answer is if you multiply a positive by a negative.
It is a negative. Always remember this: -A positive times a positive equals a negative -A negative times a negative equals a positive -A negative times a positive equals a negative *This works ONLY for addition and multiplication I hope this info helped you! :)
Nonlinear can be only positive or only negative, or switch between the two over its domain.
Yes, the only time a quotient is negative is when a negative and a positive number are divided.
Only positive.
No. If both parents are A negative the child can only be A negative or O negative. If the child is AB positive at least one parent must have type B or AB blood and at least one must be RH positive.
