In the desert, a 2 L container of Gatorade at 42°C is in a cooler that initially contains 1 kg of ice (and no liquid water), which is closed and perfectly insulated from the surroundings. Assuming that the Gatorade has temperature- and pressure-independent density and specific heat of 1 kg/L and 4.3 kJ/(kgK), respectively, what is the maximum temperature of the ice required to cool the Gatorade to 1°C? Assume that the properties of the ice can be evaluated at 0°C, and are independent of temperature. Neglect a) the presence of any air in the cooler and b) the mass of the containe

What is work? how much work is done to move an object 0 meters?

Ihave a density of 1.61g/cm^3 and a mass of 28g. find the missing value

Cells in the nervous system have a potential difference of 70 mv across the cell membrane separating the interior of the cell from the extracellular fluid. this potential difference is maintained by ion pumps that move charged ions across the membrane. is this an emf? select the correct answer and explanation. 1)no. the ion pumps cannot separate charges; thus, they cannot create a potential difference. 2)yes. the ion pumps cannot separate charges, but they still can create a potential difference. 3)yes. the ion pumps can actively separate charge; thus, they can create a potential difference. 4)no. the ion pumps can separate charges, but they cannot create a potential difference.
