Is ironing clothes conduction, convection or radiation
choli [55]

Ironing clothes is Conduction.

<h3>What is Conduction? </h3>

Conduction is one of the means of Heat transfer ,others includes

  • Convection
  • Radiation

Conduction is the transfer of heat energy from one object to another object from particles in a hotter object to particles in a cooler object, For Example: Ironing clothes is conduction.

This is because The heat from the iron which transfers to the clothes is conduction.

In a laboratory preparation room one may find a reagent bottle containing 5.0 L of 12 M NaOH. Write a set of instructions for th
kari74 [83]

<u>Answer:</u> The volume taken from the reagent bottle must be 72.91 mL

<u>Explanation:</u>

To calculate the volume of concentrated solution, we use the equation:

M_1V_1=M_2V_2

where,

M_1\text{ and }V_1 are the molarity and volume of the concentrated solution  which is the reagent bottle.

M_2\text{ and }V_2 are the molarity and volume of diluted solution which is the solution to be prepared.

We are given:

M_1=12M\\V_1=?mL\\M_2=3.5M\\V_2=250mL

Putting values in above equation, we get:

12\times V_1=3.5\times 250\\\\V_1=72.91mL

Hence, the volume taken from the reagent bottle must be 72.91 mL

What is the approximate temperature of 1.4 moles of a gas with a pressure of 3.25 atmospheres in a 4.738-liter container
attashe74 [19]

Answer:

134K

Explanation:

Using the ideal gas law equation;

PV = nRT

Where;

P = pressure (atm)

V = volume (Litres)

n = number of moles (mol)

R = gas constant (0.0821 Latm/Kmol)

T = temperature (K)

Based on the information provided, n = 1.4moles, P = 3.25atm, V = 4.738L, T = ?

3.25 × 4.738 = 1.4 × 0.0821 × T

15.3985 = 0.11494T

T = 15.3985/0.11494

T = 133.969

Approximately;

T = 134K
