What's the relationship between the temperature and the density of a substance?

answer:

When you increase the temperature of a substance its volume increases.(This is also known as Charles law~> T and V are directly correlated)

When the substances volume increases its density decreases.

Density:Mass/Volume

Hope this helps:)

Answer:

As the temperature increase, density decreases.

Explanation:

As the temperature increases, the volume of a substance increase. The substance expands. The inter-molecular distance increases.

The volume and density are inversely related.

\text{Density}=\frac{\text{Mass}}{\text{Volume}}

As the volume increases, density decreases.

Thus, with increase in temperature, the density decreases.

katen-ka-za [31]
Answer:

The options for this question are:

1. A negligent tort because Matt was careless in throwing the rock.
2. A negligent tort because he only intended to harm Jamal.
3. An accidental tort because he struck Sally by mistake.
4. An intentional tort because Matt intended to throw the rock and physical injury resulted.
5. Matt did not commit a tort against Sally because he only intended to strike Jamal with the rock

The best answer choice is:

An intentional tort because Matt intended to throw the rock and physical injury resulted.

Explanation:
If Matt originally wanted to hit Jamal with a rock in the head but instead hit Sally who is standing directly next to Jamal, then he committed an intentional tort. This kind of tort can be transferred as the tort easer knew certainly that his plan would result in inevitable consequences.<span>

The rate at which the concentration of a drug in the bloodstream decreases is proportional to the concentration at any time t. I
Westkost [7]

Answer:

C(t) = C_oe^{-kt}

Explanation:

From the given information:

At any given time (t), let c(t) represent the concentration of the drug present in bloodstream.

Deriving the equation:

\dfrac{dC}{dt} decrease proportionally to Concentration C

i.e

\dfrac{dc}{dt} \alpha - C

\dfrac{dc}{dt} = -k C

\dfrac{dc}{c} = -k dt

\int \dfrac{dc}{c} = -k \int dt

㏑(C) = -kt + λ

where,

λ is the integration constant.

Integrating at t = 0, concentration of blood = Co g/mL

C(0) = Co

㏑(C₀) = 0 + λ

λ = ㏑(C₀)

From ㏑(C) = -kt + λ

㏑(C) = -kt + ㏑C₀

㏑(C)  - ㏑C₀ =  -kt

\dfrac{C}{C_o} = e^{-kt}

C(t) = C_oe^{-kt}

∴

The concentration of drug in blood at any time t is:

C(t) = C_oe^{-kt}

Explain why lightning strikes can be dangerous even when an individual is not directly struck.
Ber [7]

Answer:

Lightning can be best described as an electrical discharge, which is caused by the imbalances between the clouds and the storm and the ground or sometime within the cloud. It carries around 20,000 to 30,000 ampere of current when it comes to the ground.

It is not only the direct hit of the lightning that make you worry, but any strike that is close to us can be dangerous to us as it results in the release of huge amount of electricity in the surrounding area.
