The exercise is to measure and record the Physical properties of materials, such as flexibility, magnetism, thermal conductivity, electrical conductivity and density. Magnetism and flexibility can be observed directly, while density, thermal conductivity, and electrical conductivity require calculations.
The student is asked to measure and record the physical properties of various materials.
Flexibility can be rated subjectively on a scale of 1-10, with 10 being most flexible.
Magnetism can be tested by seeing how many paper clips each material can hold.
Thermal Conductivity (W/(m·K)) is a measure of a material's ability to conduct heat, while Electrical Conductivity (x107 S/m) measures the material's ability to conduct electricity.
For density, you need the mass (M) and volume (V) of the material.
The mass is given as 10g for all materials. You have to measure the volume (V) using the formula length x width x height (L x W x H).
Then plug M and V into the density formula D=M/V to get the density in g/cm3. Keep in mind that each material will have different properties.

The concentration pertains to the molarity of the solution with an equation of mol of solution per liter of solvent.
M (molarity) = moles of solute/L of solvent
M (molarity) = 0.5 mol NaOH / 0.5 L
M (molarity) = 1 M NaOH

The equation for power is,
Power
Where P is power is Watts
I is current in Amperes
V is voltage in volts
Given, power of the camcorder = 16 Watts
Output voltage from its battery = 8 Volts
Calculating the current in Amperes from power and voltage,
I =
= 2 A
Therefore the current used will be 2 A.
Power is defined as product of current multiplying voltage, that is
P=I×V
Here, P is the power,
I is the current
While V is the voltage
Here,
P is 16 watt
V is 8 volt
I is the current, that needs to be determined,
Putting the values in the equation
16=I× 8
I=2
So, When a camcorder has a power rating of 16 watts. If the output voltage from its battery is 8 volts, what current is 2 A

Answer : Evaporative salts are majorly used as common salts or halites, which are highly and widely used to preserve foods, dye fabric, and de-ice roads.
Explanation : Evaporative salts are produced by evaporation of the sea water hence it is named as evaporative salts. These are mainly extracted through evaporation from seawater. The salts from shallow ponds where the seawater gets collected in a land, which is later harvested and then purified.
