If the specific heat of methanol is 2.51 j/k-g, how many joules are required to raise the temperature of 50 g of methanol from 20oc to 70oc?

The amount of heat required is 6275 J

Explanation:

To calculate the change in temperature, we use the equation:

where,

q = heat absorbed = ?

m = mass of methanol = 50 g

c = specific heat capacity of methanol = 2.51 J/g.K

= change in temperature =    (change remains the same)

Putting values in above equation, we get:

Hence, the amount of heat required is 6275 J

terd muffin is the correct answer

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
