Answer: 319.9g

Explanation:

Mass of graduated cylinder with water = 534.26g

Mass of  graduated cylinder = 214.36g

Mass of just water = Mass of graduated cylinder with water - Mass of graduated cylinder.

Mass of just water = 534.26g  -  214.36 g =  319.9g

How many joules of energy are necessary to heat a sample of water with a mass of 46.0 grams from 0.0 to 100.0
Luba_88 [7]

Answer:

Q = 19255.6 j

Explanation:

Specific heat capacity:

It is the amount of heat required to raise the temperature of one gram of substance by one degree.

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

Given data:

Mass of water = 46 g

change in temperature = ΔT = 100-0.0 = 100 °C

Heat absorbed by water = ?

Solution:

Specific heat capacity of water = 4.186 j/g. °C

Q = m.c. ΔT

Q = 46 g×4.186 j/g. °C×100 °C

Q = 19255.6 j

ValentinkaMS [17]

C) landslides.

Explanation:

Landslides is not a way in which mountains are built on earth. It is a destructive process in nature that causes the slumping and wasting of land masses.

Landslide is a form of mass wasting and does no build masses.

Volcanoes helps to build mountains on the crust and this way, igneous rocks are formed.

Deposition process upbuilds to form sedimentary rocks.

Faulting is a can also be a constructive process that builds a mountain in the case of horsts and graben
