Kelvin

Kelvin

(Science: unit) a temperature scale where zero degrees corresponds to absolute zero (no thermal energy), degrees have same size as in Celsius/centigrade scale. 273.16 k = zero c, 373.16 = 100 c.

Abbreviation: k British physicist who invented the kelvin Scale of temperature and pioneered undersea telegraphy (1824-1907).The basic unit of thermodynamic temperature adopted under the Systeme international d'Unites.A unit of measurement where one kelvin equals one degree Celsius, and 0 Kelvin's is absolute zero (-273.15 celsius).

Re: SOS...please help, Na+/H+ pump problem

... pump is disabled. So, what you need to know is: Since Vm = -70mV [H+]in =6.3 *10^-8 M [H+]out=4*10^-8 M [Na+]in=12mM [Na+]out=145mM T=37C or 310 Kelvin R=1.987 cal/mol-deg K Vm=-70mV or -0.07V Faraday=23063 cal/mol-volt using nernst equation Ev=(RTln[Xout]/[Xin])/F you have: -70=(1.987*310*ln(145/[Nain])/23063 ...

SOS...please help, Na+/H+ pump problem

... each Na+ that moves across the membrane? Use the following data: [H+]in =6.3 *10^-8 M [H+]out=4*10^-8 M [Na+]in=12mM [Na+]out=145mM T=37C or 310 Kelvin R=1.987 cal/mol-deg K Vm=-70mV or -0.07V Faraday=23063 cal/mol-volt I assume you use one of the following equations though I not 100 percent ...

Free Energy of the Universe

Isn't the temperature of space 3 kelvin, and at one piont would of been over 100 kelvin, so the energy is beening lost as space exspands. ^^ energy dont get "lost" does it? i was laways tought energy just get turned into different forms. ...
