Somebody help please?? I’ll mark brainlist!! About how much energy is needed to
increase the temperature of 5 kg of sand
from 18°C to 32°C if the specific heat of
the sand is 190 J/kg • "C?

Heating 1.30 Kg of sand 70 degrees Celsius takes 80,000 Joules of heat.

Explanation:.

Step-by-step explanation:

The amount of heat required to warm a substance is determined using heat capacity. The equation below allows us to solve for the heat released or absorbed when warming a substance.

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
