when carbon dioxide is frozen it is called dry ice in order to keep it frozen the tempter has to be -109.3 fahrenheit or lower fahrenheit is 9/5 of the celsius tempter plus 32 degrees write an inequality to determine the celsius tempetures C at which dry ice can be kept

Respuesta :

Degrees Celsius = (Fahrenheit -32) * 5/9
Degrees Celsius = (-109.3 -32) * 5/9
Degrees Celsius = -141.3 * 5/9
Degrees Celsius = -78.5

Therefore dry ice must be kept at a temperature of < = -78.5 Celsius
