3 0

In this experiment you will determine the density of an unknown liquid. You will measure the mass of a known volume delivered from a pipet and use the expression:

<span><span><span>M
V</span></span><span>D=</span><span /></span>

where D = density, M = mass and V = volume to calculate the density of the unknown liquid.

Which temperature most likely corresponds to the asthenosphere?
iren2701 [21]

Answer:

A. 1613 °C

Explanation:

The asthenosphere is located just below the Earth’s crust.

It must be molten or semi-molten, so that convection currents can move the tectonic plates above it.

Rocks start to melt at about 1300 °C, so a temperature of 1613 °C sounds about right.

Why is it important for an engineer who is designing a new home-cooling/heating system to have knowledge about the transfer of h
Masteriza [31]

Cooling and heating system involves the collection and dissipation of heat appropriately. Heat gradient is important for heat transfer between systems because heat travels from the warmer system to the cooler system. The right medium for heat transfer is also important for this exchange – A good conductor of heat is required.

Identify whether each reaction represents a chemical reaction or a nuclear reaction by filling in the blank with the word ‘chemi
valkas [14]
A chemical reaction is defined as the reaction between two or more substances that produces new substances/compounds.

On the other hand, a nuclear reaction is a reaction that alters the nucleus of a certain atom. This can be done either by splitting the nucleus or by joining this nucleus with another one.

Reaction 1:
Cl₂ + H₂ ............> 2 HCl
This is the combination of two elements to produce a new compound.
Therefore, this reaction is a chemical reaction

Reaction 2:
²₁H + ³₁H .........> ⁴₂H + ¹₀n
This is an alteration in the nucleus of a hydrogen atom by bonding it with another nucleus.
Therefore, this reaction is a nuclear reaction

Hope this helps :)
