Answer: 7.2 ounces

Explanation:

1) Data:

- glass size: 9-ounce

- content of vitamin C: 72 milligrams


- glasssize: x

- content of vitamin C: 60 milligrams


2) Proportion


9 ounces / 75 mg = x / 60 mg


3) Solution:


9 ounces × 60 mg = 75 mg × x


⇒ x = 9 ounces × 60 mg / 75 mg = 7.2 ounces

What quantity of heat is required to raise the temperature of 460g of aluminum from 15C to 85C?

Hoochie [10]

Answer:

Q = 28.9 kJ

Explanation:

Given that,

Mass of Aluminium, m = 460 g

Initial temperature, $T_i=15^{\circ} C$

Final temperature, $T_f=85^{\circ}$

We know that the specific heat of Aluminium is 0.9 J/g°C. The heat required to raise the temperature is given by :

$Q=mc\Delta T\\\\Q=mc(T_f-T_i)\\\\Q=460\ g\times 0.9\ J/g^{\circ} C\times (85-15)^{\circ} C\\\\Q=28980\ J\\\\\text{or}\\\\Q=28.9\ kJ$

So, 28.9 kJ of heat is required to raise the temperature.
