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

$\frac{x}{1cm} = \frac{0.03}{1m} \\ \\ = \frac{0.03}{100cm} =\frac{0.0003}{1cm}$

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

$=0.03\frac{W}{m*c}$

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

$=0.03\frac{W}{1m*c}$

we can replace 1m as 100cm

$=0.03\frac{W}{100cm*c}$

now, we can simplify it

$=0.0003\frac{W}{cm*c}$

so, thermal conductivity is

$=0.0003\frac{W}{cm*c}$................Answer
