Question

the batting wang xiu ying uses to fill quilts has a thermal conductivity rate of 0.03 watts (W) per meter(m) per degree celsius. what is the batting thermal conductivity when w/cm•c

Answer 1

Given that the batting wang xiu ying uses to fill quilts has a thermal conductivity rate of 0.03 watts (W) per meter(m) per degree celsius.

Let the batting conductivity in W/cm°c be x, then


`(x)/(1cm) = (0.03)/(1m) \\ \\ = (0.03)/(100cm) =(0.0003)/(1cm)`

Therefore, the batting conductivity in W/cm°c is 0.0003 W per cm per degree celcius.

Answer 2

We are given

a thermal conductivity rate of 0.03 watts (W) per meter(m) per degree celsius

so, thermal conductivity is

`=0.03(W)/(m*c)`

while we want the batting thermal conductivity in w/cm•c

The only difference is that metre and cm

so, we need to change metre into centimeter

we know

1m =100cm

so, we can write thermal conductivity as

`=0.03(W)/(1m*c)`

we can replace 1m as 100cm

`=0.03(W)/(100cm*c)`

now, we can simplify it

`=0.0003(W)/(cm*c)`

so, thermal conductivity is

`=0.0003(W)/(cm*c)`................Answer
