The cooler the temp of the star the star would appear to glisten a red. if the star is warmer the star would be a light blue or blue. An example would be the tiny red dwarf stars. they only have 7% of the suns heat so they appear red.

Bob is cleaning his dishwasher with white vinegar by putting a bowl of this ____________ mixture in the top of an empty dishwash

Maurinko [17]

Answer: Baking Soda

A mixture of white vinegar and baking soda in a bowl will produce a paste that is helpful in removing stains and sanitizing a dishwasher. To meticulously clean your dishwasher, spread the mixture onto the build-up crust in the bottom basin of the washer itself then let it sit for 15-20 minutes before running a short cycle using the hottest water. The baking soda will further absorb the unpleasant odors and will leave your dishwasher smell fresh.

Describe the relationship between the pressure and volume of a gas when temperature and mass are constant

mr_godi [17]

Answer:

The product of Pressure and Volume is a constant.

Explanation:

We know the Ideal gas equation,

PV = nRT,

where,

P - Pressure of the gas

V - Volume of the gas

n - No. of moles of the gas taken

R - Universal Gas Constant.

T - Temperature of the gas.

We know that , n = $\frac{wt}{Mwt}$

where, wt - Mass of gass ; Mwt - Molecular weight of the gas.

We are given the weight of the gas remains constant (wt is a constant)

Therefore as n = $\frac{wt}{Mwt}$ ,(where both wt and Mwt are constants)

n is a constant in this process.

Universal gas constant is a constant

Given temperature is a constant.

Therefore,

As, PV = nRT, (where n,R,T are constants),

PV is a constant.

Therefore we can say,

PV = k, for some constant k.

If we plot a graph for P vs V , we get a Rectangular Hyperbola( One of the general forms of a Rectangular Hyperbola is xy = c)
