How much heat energy is required to raise the temperature of 0.360 kg of copper from 23.0 ∘C to 60.0 ∘C? The specific heat of co
AVprozaik [17]
MThe  heat  energy  required  to  raise  the  temperature   of  0.36Kg   of  copper   from   22 c   to  60  c  is  calculate  using  the  following  formula

MC delta T
m(mass)=  0.360kg  in  grams  =  0.360  x1000 = 360 g
  c(specific  heat  energy)  =  0.0920  cal/g.c
delta T =  60- 23  = 37  c

heat  energy is therefore=  360g   x0.0920 cal/g.c  x 37  c=  1225.44  cal

What would happen if there was no sodium potassium pump?
vladimir1956 [14]
The sodium-potassium pump (NaK) is very important for the function of the most cellular process in the body, It's responsible for the movement of the K ions into the cell and the movement of the Na ions outside the cell at the same time.
It's important for excitable cells such as a nerve cell, the pump helps it with transmitting pluses. It also important in controls cardiac contractions and control blood pressure. It plays an important role in maintaining the sodium and potassium balance in the body in the kidneys.So the Cell function will be affected badly if there was no sodium-potassium pump.
