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.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
