Conduction, because there is a direct transfer of heat.
When the iron touches the fabric, the heat from the iron gets transferred to the fabric and this is why it is a conduction type of heat transfer.
Light travels at precisely <span>299,792,458 metres every second (abbreviated to 3 x 10^8 metres every second but let's be precise)
There are 60 seconds in every minute (</span><span>299 792 458 x 60 = 17,987,547,480m)
60 minutes in every hour (17,987,547,480 x 60 = 1,079,252,849,000m)
96 hours in 4 days (</span><span>1,079,252,849,000 x 96 = 10,360,827,350,000m)
</span><span>Now let's convert to km to make this number (slightly) more manageable
(</span>10,360,827,350,000 / 1000 = <span>103,608,273,500km)
</span>Light travels <span>103,608,273,500km in 4 days - that's the equivalent of going around the equator of the earth 813,124 times!</span><span>

Answer: 2.4 M
Explanation:
According to the neutralization law,
where,
= molarity of 
solution = 3.5 M
= volume of 
solution = 34.3 ml
= molarity of 
solution = ?
= volume of solution = 50 ml
= valency of = 1
= valency of = 1
Therefore, the concentration of NaOH solution is 2.4 M.
Because people make those substance out of other things
