When air pressure is low it is Cold
Answer:
Because sodium and potassium are very reactive metals so they react explosively with HCL and H2SO4 evolving a large amount of heat.
Explanation:
Answer:
c) No, because Celsius is not an absolute temperature scale
Explanation:
converting 5 oC to kelvin which is the absolute temperature scale gives = 273 + 5 = 278 K
and converting 20 oC to kelvin = 20 + 273 = 293 K
the ratio = 278 / 293 = 0.94 approx 1 not 4
