An insulated thermos contains 140 cm3 of hot coffee at 85.0°c. you put in a 15.0 g ice cube at its melting point to cool the coffee. by how many degrees has your coffee cooled once the ice has melted and equilibrium is reached? treat the coffee as though it were pure water and neglect energy exchanges with the environment. the specific heat of water is 4186 j/kg·k. the latent heat of fusion is 333 kj/kg. the density of water is 1.00 g/cm3.

Explanation:

Here at thermal equilibrium we can say that thermal energy given by Hot coffee is equal to the thermal energy absorbed by ice cubes

So here we have

now since ice cubes are added into coffee when it is at melting temperature

So here we can say that final temperature of coffee is T degree C

Now we have

here we have

L = 333 kJ/kg = 333 J/g[/tex]

now we have

step-by-step explanation:

we are given

we have to simplify it

firstly, we will factor it

now, we can cancel like terms

now, we can combine it

so, we get

the expression 15n + 2(3p) represents the amount isaiah spent buying gasoline and snacks, where n represents the price of each gallon of gasoline and p represents the cost of each snack that he bought. which statement is true about the amount isaiah spent?
