Which property helps to explain differences in the specific heat capacities of
tatyana61 [14]

Answer:

D. Forces between molecules

Explanation:

Specific heat capacity of water can be defined as the amount of heat a gram of water must lose or absorb in order to change its temperature by a degree Celsius. It is measured in Joules per kilogram per degree Celsius (J/kg°C). Generally, the specific heat capacity of water is 4.182J/kg°C and is the highest among liquids.

Mathematically, the specific heat capacity of a substance is given by the formula;

c = \frac {Q}{mdt}

Where;

Q represents the heat capacity or quantity of heat.

m represents the mass of an object.

c represents the specific heat capacity of water.

dt represents the change in temperature.

Cohesion is a property of water and it typically refers to the attraction between molecules of water which holds them together.

In Science, the property which helps to explain differences in the specific heat capacities of two substances is the forces between molecules.

This ultimately implies that, the more closely bonded the atoms of a substance are, the higher or greater would be the substance's specific heat capacity. Thus, it varies for the various states of matter i.e solid, liquid and gas.

Is the following chemical equation balanced?<br><br> MgI2 + Br2 MgBr2 + I2 <br><br> yes<br><br> no
Brums [2.3K]

Yes

Explanation:

This chemical equation:

Mg I_2 + Br_2 \rightarrow Mg Br_2 + I_2

is balanced, because the number of atoms of each element is the same on the reactant side and on the product side. In fact:

- Mg: one atom on the left, one on the right

- I: 2 atoms on the left, and 2 on the right

- Br: 2 atoms on the left, and 2 on the right

So, the reaction is balanced.

Calculate the displacement and velocity at 2.00 s for a ball thrown straight up with an initialvelocity of 15.0 m/s. Take the po
Hunter-Best [27]

Answer:

The displacement, velocity and time is 20.4 m, -4.52 m/s and 3.624 sec.

Explanation:

Given that,

Initial velocity =15.0 m/s

Height = 10 m

We need to calculate the displacement at 2 sec

Using equation of motion

s=ut-\dfrac{1}{2}gt^2+s_{0}

Put the value into the formula

s=15t-\dfrac{1}{2}\times9.8\times t^2+10

At 2 sec,

s=15\times2-\dfrac{1}{2}\times9.8\times4+10

s=20.4\ m

We need to calculate the time

Using equation of motion again

s=15t-\dfrac{1}{2}\times9.8\times t^2+10

At ground s = 0,

15t-\dfrac{1}{2}\times9.8\times t^2+10=0

4.9t^2-15t-10=0

t = 3.624\ sec

Neglect the negative term because the time is not negative

We need to calculate the velocity

Using formula of velocity

v=u-gt

v=15-9.8\times3.624

v=-4.52\ m/s

Hence, The displacement, velocity and time is 20.4 m, -4.52 m/s and 3.624 sec.
