The total heat required to convert the ice to steam is 155,000 J.
The given parameters:
- <em>Mass of the ice, m = 50 g</em>
- <em>Initial temperature of the ice, t = -10 ⁰C</em>
- <em>Final temperature of the ice, T = 0⁰C, 100⁰C and 120⁰C</em>
- <em>Specific heat capacity of water = 4.184 J/g⁰C</em>
- <em>Heat of fusion of ice, = 333.55 J/g</em>
- <em>Heat of vaporization, = 2,230 J/g</em>

Explanation:
Critical thinking and skepticism are important to scientific inquiry because they help scientists to thoroughly examine all evidence before making their conclusions, this allows them to avoid errors. Critical thinking refers to the attitude of asking questions constantly, thoroughly examining information and evidence and making valid conclusions. While skepticism refers to an attitude of doubt. These attitudes are very important in scientific investigations; it helps scientists to be able to provide good evidence on which they base their conclusions.
