Answer
The specific heat of the glass = 0.7366 J/g°C
Explanation
Given:
Mass of the glass sample, m = 9.3 g
Quantity of heat given off, Q = 87 J
Change in temperature, ΔT = 12.7 °C
What to find:
The specific heat, c of the glass.
Step-by-step solution:
The specific heat, c of the glass can be calculated using the given formula below.
Putting the values of the given parameters into the formula, we have;
Therefore, the specific heat of the glass is 0.7366 J/g°C
Explanation:
Boiling water:water heats up and bubbles physical change
Baking a cake: starts to cook into bread chemical change
Burning wood: turns into ash and burned wood chemical change
Painting a door: door changes color physical change
Usually water because the reaction amino acids do is hydrolysis, which joins 2 molecules together to from 1 larger compound and a water molecule<span />
<span>Earth's gravitational potential energy: GPE = mgh = Gravity (9.81m/s2) × Mass (kg) × Height (m)
it's k</span><span>inetic energy</span>
