Answer:
Sea level rise is caused by several different processes, including melting ice. But one big contributor to sea level rise is increasing global temperatures, which heat seas and cause something called thermal expansion of water. Thermal expansion happens when water gets warmer, which causes the volume of the water to increase. About half of the measured global sea level rise on Earth is from warming waters and thermal expansion.

Explanation:
Specific heat capacity is an intensive physical property of matter. It is a measure of the quantity of heat that must be supplied in order to change the temperature of a unit mass of a substance by 1°C.
The specific heat capacity of a substance determines the quantity of heat that must be supplied in order to effect a temperature change of a unit mass of a substance. The higher the specific heat capacity of a substance, the greater the quantity of heat required to effect a temperature change in a given mass of the substance.
The specific heat capacity of water is 4,200 Joules per kilogram while the specific heat capacity of copper is 385 Joules per kilogram. Hence, the heat capacity of water is far greater than that of copper and consequently, 50 g of copper require less heat (q) than 50 g of water, in order to raise the temperature by 15 oC.
Answer:
317.46 °C
Explanation:
The expression for the calculation of heat is shown below as:-
Where,
is the heat absorbed/released
m is the mass
C is the specific heat capacity
is the temperature change
Thus, given that:-
Mass of lead = 118.5 g
Specific heat = 0.129 J/g°C
Initial temperature = 10 °C
Final temperature = x °C
Q = 4700 J
So,
<u>Thus, the final temperature is:- 317.46 °C</u>
Answer:
10 moles
Explanation:
of moles = given mass /atomic mass = 280 g /28 g = 10 moles of Si atoms in 280g sample.
