What will happen to the temperature, as thermal energy is added to the ice over time? OK

Answer:

When you heat ice, its temperature rises, but as soon as the ice starts to melt, the temperature stays constant until all the ice has melted. This happens because all the heat energy goes into breaking the bonds of the ice's crystal lattice structure.

Explanation:

Shards of ice fly from the sculptor’s chisel. As the crowd

looks on, a swan slowly emerges from a massive block of ice. As

the day wears on, however, drops of water begin to fall from the

sculpture. Drip by drip, the sculpture is transformed into a puddle of liquid water. What makes matter change from one state to

another? To answer this question, you need to think about the

particles that make up matter.

Energy Simply stated, energy is the ability to do work or cause

change. The energy of motion is called kinetic energy. Particles

within matter are in constant motion. The amount of motion of

these particles depends on the kinetic energy they possess. Particles

with more kinetic energy move faster and farther apart. Particles

with less energy move more slowly and stay closer together.

The total kinetic energy of all the particles in a sample of

matter is called thermal energy. Thermal energy, an extensive

property, depends on the number of particles in a substance as

well as the amount of energy each particle has. If either the

number of particles or the amount of energy in each particle

changes, the thermal energy of the sample changes. With identically sized samples, the warmer substance has the greater thermal energy. In Figure 7, the particles of hot water from the hot

spring have more thermal energy than the particles of snow on

the surrounding ground.

klio [65]
The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element. The dimensionless standard atomic weight instead refers to the AVERAGE of atomic mass values of a typical naturally-occurring mixture of isotopes for a sample of an element.
You can count it by yourself using formula

m = ({first isotopic distribution%}× {first atomic.mass})+ ({second isotopic distribution%}× {second atomic.mass}) / {100}

The following combinations are not allowed. If n and ml are correct, change the l value to create an allowable combination:
ololo11 [35]

The allowable combination for the atomic orbital is n=3, l=1 or 2, m_{l}=+1.

<h3>What are the three quantum numbers of an atomic orbital?</h3>

Three quantum numbers specify an atomic orbital:

- The principal quantum number, n, which is a positive integer, describes the relative size of the orbital and its distance from the nucleus.

- l is the angular momentum quantum number that is related to the shape of the orbital; l is an integer from 0 to n-1 (so n limits l ),

- $\boldsymbol{m}_{l}$ is the magnetic quantum number that prescribes the three-dimensional shape of the orbital around the nucleus; m_{l} values are integers from -l to =l(l limits ml)

For n = 3, l can have three values: 0, 1, and 2. Hence, the l value must be lower than 3. Because of m_{l}= +1, the l value must be higher than 0. Two l values are consistent with n and m_{l) values:

l= 1 or 2

Therefore, the allowable condition is n=7, l=1 or 2, m_{l}=+3.

Evgen [1.6K]

Answer:

=3,723.3 J=3.72  but if it has the option of -3.72 kJ then use that

Explanation:

Use the formula q=m×Cp×delta T

m=1.500 kg=1,500 g

Co=2.52 J/g·k

delta T=0.985k

q=(1,500g)(2.52 J/g·k)(0.985k)
