How can compact fluorescent bulbs the environment? (2 points) they will create new industry. the will use less energy overall. they will further science and technological development. they will provide society with a product that is in short supply.

Answer : fluorescent bulbs help the environment as they use less energy overall

Explanation :

Fluorescent bulbs are energy efficient. They consume less electricity as compared to conventional bulbs. They also generate less heat.

In modern world, we are facing energy crisis. The non renewable energy sources are getting depleted. It is highly necessary that we should start using alternative energy sources such as non renewable energy sources more often.

Another way to reduce our energy consumption is to use gadgets which use electricity more efficiently. One example is fluorescent bulb over traditional incandescent bulbs.

Therefore we can say that fluorescent bulbs help environment by using less energy and by producing less heat.

The specific heat of the substance is 0.739 J/g°C

The substance can be glass or SiO2

Explanation:

Step 1: Data given

Heat required = 54 J

Mass of the substance = 2.47 grams

Initial temperature = 17.10 °C

Final temperature = 46.70 °C

Step 2: Calculate the specific heat of the substance

Q = m*c¨*ΔT

⇒with Q = the heat required =54 J

⇒with m = the mass of the substance = 2.47 grams

⇒with c = the specific heat of the substance = TO BE DETERMINED

⇒with ΔT = the change of temperature = T2 - T1 = 46.70 - 17.10 = 29.60 °C

c = Q / (m*ΔT)

c = 54 / (2.47 * 29.60)

c = 0.739 J/g°C

The specific heat of the substance is 0.739 J/g°C

The substance can be glass or SiO2
