The directions in a candy recipe instruct the cook to remove the pot containing the candy mixture from heat when it reaches a temperature of 236°F. Can a Celsius thermometer with a range of –10°C to 110°C be used to determine when to remove the mixture from heat? Explain. QUICKK I HAVE A QUIZ RN ITS IN 15 MINUTES IM IN SCHOOL T. T

Explanation:

A Celsius thermometer with a range of -10°C cannot be used to determine when the soft ball stage is reached in the candy mixture.  

Temperature is most commonly measured with a thermometer that has two different scales: Fahrenheit and Celsius. Water freezes at 0°C and boils at 100°C on the Celsius scale and freezes at 32°F and boils at 212°F on the Fahrenheit scale.

Temperature of 236°F corresponds to 113.3°C. Now a Celsius scale has a maximum of 100°C on the thermometer. Hence a Celsius thermometer cannot be used to measure a temperature that corresponds to 236°F.  

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
