Answer:
A liquid
Explanation:
Liquids has an indefinite shape, which means it could change from one shape to another. For example, if you pour water into a rectangular fish tank. The shape of the liquid changes into a rectangle. Definite volume means its volume is consistent and that it is unchangeable. If you fill the rectangular fish tank with water, the volume of the water stays the same even though it changes shape.
Hope this helps.
Answer:
Given:
Mass (m) = 10.0 g
Rise in temperature (∆T) = 8.58°C
Energy required (Q) = 73.2 J
To Find:
Specific heat of the substance (c)
Explanation:
Specific heat (c) of a substance is the energy required to raise the temperature of one gram of the substance by one degree Celsius.
Formula of specific heat is given as:
By substituting value of Q, m & ∆T in the formula we get:
Answer:
Option (3) 334J.
Explanation:
The following data were obtained from the question:
Mass (m) = 1g
Heat of fusion (ΔHf) = 334J/g
Heat (Q) =?
The heat released can be obtained as follow:
Q = m·ΔHf
Q = 1 x 334
Q = 334J.
Therefore, the heat released when 1g is converted to ice is 334J.
Nitrogen, Because nitrogen is it's own element and doesn't require anything. <span />
