Explanation:
It is mainly the very low density of gases that make them bad conductors of heat. In liquids and solids atoms and molecules are densely packed and transfer of energy has much smaller distances to happen.

Answer:
c.The value of T at Recording Station N would be greater than T at Recording Station S.
Explanation:
We can deduce from the information provided that the value of T at recording station N would be greater than T at recording station S.
This problem relates distance with time.
Speed = 
Distance = Speed x time
- Just like any other physical quantity, speed of a substance is directly related to time.
- The larger the time taken the farther the distance it will cover assuming the velocity is constant.
- Earthquake waves for example moves at constant speed with a unique velocity in earth materials.
- The farther the distance, the more time it will take to reach the seismic recording station.
- Since N is a distance of 200km from the epicenter, it will take a greater time and have a higher reading of T to reach the station.
Answer:
you can correct it by adding an acid to make it neutral or less basic
To determine the strength of potassium permanganate with a standard solution of oxalic acid.
The volume at STP : 9.856 L
<h3>Further explanation</h3>
Given
Mass of ethane : 13.21 g
Required
The volume at STP
Solution
Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters / mol.
mol ethane(C2H6) :
= mass : molar mass
= 13.21 g : 30 g/mol
= 0.44
Volume at STP :
= 0.44 x 22.4 L
= 9.856 L
